Answer
C= - 12, B= 5
Step-by-step explanation:
FOIL METHOD
2x^2+8x-3x-12
2x^3+5x-12
A=2
B= 5
C= - 12
answers
B. 5
D. -19
Step-by-step explanation:
FOIL METHOD
(2x-3)(x+4)=7
2x^2 + 8x - 3x -12 =7
2x^2 + 5x - 12 - 7=0
2x^2 + 5x - 19 =0
a= 2
b= 5
c= -19
use the form ax^2 + bx + c = 0 to identify a, b, and c
