Question

find the solutions of the system
y = x² + 3x – 4
y = 2x + 2

Answer 1

(–3, 6) and (2, –4)
(–3, –4) and (2, 6)
(–3, –4) and (–2, –2)
no solution

Answer 2

y = x² + 3x – 4
y = 2x + 2
--------------------------------
x² + 3x – 4= 2x + 2

x^(2)+3x-4=2x+2

x^(2)+x-4=2

x^(2)+x-6=0

(x+3)(x-2)=0

x+3=0_x-2=0

x=-3,2

Answer 3

(–3, –4) and (2, 6)

Answer 4

Option B
