enter your answers as a comma-separated list
(x + 7)(x - 2) = -20
x2-2x+7x-14 = -20
x2+5x+6 = 0
x2+2x+3x+6 = 0
x(x+2)+3(x+2) = 0
(x+2)(x+3) = 0
x=-2, x= -3
x = 2b(4b + 5)
if x=-2
8b2+10b+2 = 0
8b2+8b+2b+2 =0
8b(b+1)+2(b+1)=0
(b+1)(8b+2)=0
b=-1/4, b=-1
if x=-3
8b2+10b+3 = 0
8b2+4b+6b+3 =0
4b(2b+1)+3(2b+1)=0
(2b+1)(4b+3) = 0
b = -1/2 , b = -3/4
So value of b = -1,-1/4,-1/2,-3/4.
Please provide feedback.Thumbs up.Thanks.
