a) We know that, for a general quadratic equation that can be written as : ax²+bx+c=0, the sum of its roots (S) is equal to -b/a and the product of its roots (P...

We have a system of n linear equations incorporated by Ax = b, with A being a n x p matrix of numeric coefficients, x being a p-dime...

Will need a whiteboard so I can draw a matrix to fully explain.

dy/dx=6x+7

6x+7=0

x=-7/6

Sub back into original equation; y=98/6
