Answer:
-3, 6
Step-by-step explanation:
(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6
Y - 0.32y = (1 - 0.32)y = 0.68y
Answer:
-87= 1 + 8x
-88= 8x
x= -11
Basically bring over the one to the other side of the equation and solve for x by dividing.
