1. Reduce <span>3x2-6x-240 to x^2 - 2x - 80
2. Use " ^ " to indicate exponentiation
3. Factor </span>x^2 - 2x - 80 using completing the square:
x^2 - 2x + 1^2 - 1^2 - 80
(x+1)^2 - 1 - 80
(x+1)^2 - 81
(x+1)^2 - 9^2 = (x+1-9)(x+1 +9), or (x-8)(x+10)
Final answer, with all factors shown: 3(x-8)(x+10)
Answer:
Step-by-step explanation:
V = L*w*h
L = 3
w = 2
h = ?
V = 24
24 = 2*3 * h Combine the right
24 = 6* h Divide both sides by 6
24/6 = 6h/6
4 = h
