Question

Find the solutions of the following system of equations.

y = x² + 3x – 4
y = 2x + 2

Answer 1

If you factor the top equation you find it has only 2 roots. 1 and -3. Only 1 will work in the second one

Answer 2

y = x² + 3x – 4
y = 2x + 2

2x + 2 = x² + 3x – 4
x² + x -6 =0
(x+3)(x-2)=0
x=-3 or 2
for x=-3, y=2(-3)+2 = -4
for x=2, y=2(2)+2 = 6

Answer 3

whoops :S
