I want a pseudo code for the following 1) A pseudo to write

Resolved Question:

I want a pseudo code for the following:

1) A pseudo to write a program that can solve simultaneous equation of two variables 2) Pseudo to write a program that will add 2 matrices together 3) Pseudo code to write a program to subtract two matrices 4) pseudo code to write a program that can solve a quadratic equation.

Please, Its on Qbasic that I want to write the program, so the pseudo code should be one that i can use on Qbasic.

Algorithms can be expressed with pseudo-code. But they can also be written in simple words. Here is an analysis and algorithm.

1) Analysis.

To solve a linar equation, like this:

where a11, a12, a21, a22, b1, b2 - some fixed numbers and x1, x2 are unknowns,

one should use this formula:

to find X1:

to find X2:

The divisor can't be zero:

So we should check the divisor first, then try to find values.

The algorithm is:

- ask user to input known coefficients: a11, a12, a21, a22, b1, b2

- calculate D, that is a11*a22 - a12*a21

- if D is zero - the equation can't be solved

- if D is non zero - calculate x1 and x2 according to the above formula

2) Analysis.

Only matrices of the same dimentions can be added. Let N is a number of rows, M is a number of columns. Sum of matrices A and B is a matrix C, that has the same dimentions NxM and in the position of any row i and column j there is a sum of corresponding elements (i,j) of matrices A and B.

so the algorithm is:

- create matrix C with the same dimentions as A and B

- for every row and column of matrix C set element to be equal the sum of appropriate elements of A and B, i.e. C(row, column) = A(row, column) + B(row, column)

3) Subtraction of matrices is basically the same as addition. C(row, column) = A(row, column) - B(row, column).

4) Quadratic equation looks like:

a*X^2 + b*X +c = 0

a, b and c are numbers, X is unknown variable

there is a known formula to calculate unknown X:

X = (-b +/- SquareRoot(b^2 - 4*a*c))/(2*a)

This equation may have 1, 2 or 0 solutions depending on this expression value: (b^2 - 4*a*c). If it is equal to 0, there is only one solution:

X=(-b)/2*a

If it is below zero - there are no solutions

If it is above zero - there are 2 solutions

X= (-b + SquareRoot(b^2 - 4*a*c))/(2*a)

and

X= (-b - SquareRoot(b^2 - 4*a*c))/(2*a)

Algorithm.

- ask user to enter a, b and c

- calculate d = (b^2 - 4*a*c)

- if d<0 print a message that there are no solutions

- if d=0 print a message that there is only 1 solution, X=-B/(2*a)

- if d>0 print a message that there are 2 solutions: X=(-B+square_root(D))/(2*a) and X=(-B-square_root(D))/(2*a)

Ask-a-doc Web sites: If you've got a quick question, you can try to get an answer from sites that say they have various specialists on hand to give quick answers... Justanswer.com.

JustAnswer.com...has seen a spike since October in legal questions from readers about layoffs, unemployment and severance.

Web sites like justanswer.com/legal ...leave nothing to chance.

Traffic on JustAnswer rose 14 percent...and had nearly 400,000 page views in 30 days...inquiries related to stress, high blood pressure, drinking and heart pain jumped 33 percent.

Tory Johnson, GMA Workplace Contributor, discusses work-from-home jobs, such as JustAnswer in which verified Experts answer people’s questions.

I will tell you that...the things you have to go through to be an Expert are quite rigorous.
