How to get the x intercept y=(2x+3)(x-1)(x-4)

1 answer:

5 0

Well, to get the x intercept you have to substitute 0 for y and solve for x, and get rid of the parenthesis ( y=2x+3*x-1*x-4 ) unless you want three different x-intercepts. So if you do want those three intercepts, leave the parenthesis.

The given equations are
5x + 7y = 7
3x - 2y = 9

As a matrix equation,
A = [5 7
3 -2]

X = [x
y]

C = [7
9]
That is
a =5, c=7; and b=3, d=-2

a - b + c + d = 5 - 3 + 7 + (-2) = 7
