a) Given the following equations: 5x + y = 16 2x + y = 7 Set up the equations in matrix algebra form. Solve for x and y by premultiplying both sides of the equation by the inverse of the square matrix, (using the rules for computing the inverse of a 2 x 2 matrix given in class). b) Given the following equations: 5x + 2y = 9 10x + 4y = 18 Attempt to solve...

How does 10x^2(5x - 2) + 2x(5x - 2)^2 simplify/factor
to 4x(5x - 2)(5x - 1) ?
Would just like to know step by step how it simplifies
that way. Thanks
