Answer:
Step-by-step explanation:
O
3x² - 11x - 4 = 0
a = 3 ; b = -11 , c = -4

W
8x² + 12x = -1
8x² + 12x + 1 = 0
a = 8 ; b = 12 ; c = 1

L
x² + x = 6
x² + x - 6 = 0
a = 1 ; b= 1 ; c = -6

G
x²- 2x - 2 =0
a = 1 ; b = -2 ; c = -2

E
4x - 5 = -4x²
4x² + 4x - 5 = 0
a = 4 ; b = 4 ; c = -5

B
12x² +x -6 = 0
a = 12 ; b = 1 ; c = -6

R
2x² + 5x - 25 = 0
a = 2 ; b = 5 ; c = -25

A
6x² -5x - 4 = 0
a = 6 ; b = -5 ; c = -4
