2x +4)° 2x-9)°= 4x 2 +8x−9=3
Pull out like factors :
2x + 4 = 2 • (x + 2) (4 • (x + 2) • x) - 9
4x • (x + 2) - 9
Factoring 4x2+8x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is 8 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
-9 + 4 = -5
-6 + 6 = 0
-4 + 9 = 5
-3 + 12 = 9
-2 + 18 = 16
-1 + 36 = 35
x=3
Answer:
y = x^2 + 8x + 16
y = x + 6
x^2 + 8x + 16 = x + 6
x^2 + 7x + 10= 0
(x + 5)(x+2) = 0
x = -5
x = -2
y = (-5)^2 + 8(-5) + 16
y = 25 - 40 + 16
y = 41 - 40
y = 1
y = -5 + 6= 1
y= (-2)^2 + 8(-2) + 16
y = 4 - 16 + 16 = 4 + 0 = 4
y = -2 + 6 = 4
Point of intersection: (-2, 4)
