Answer:
WAIT WHAT
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
Answer: x = -8, y = 13
Step-by-step explanation:
x+y=5
3x+y=-11
now subtract the two equations
x-3x+y-y=5-(-11)
-2x=16, x = -8
now substitute
-8 + y = 5, y = 13

answer is c on edge
Answer:
g(x) = x(x - 5)(x + 4)
Step-by-step explanation:
Here the binomial is x + 4, indicating that a root is -4. Note that x is common to all terms of g(x)=x3−x2−20x, so we can immediately write g(x) in partially factored form as
g(x) = x(x^2 - x - 20). Since -20 = -5*4,
g(x) = x(x - 5)(x + 4)
