Answer:
y =96
Step-by-step explanation:
y =96
3 * (x^2) = 15x
3x^2 -15x = 0
x= - -15 +- sq root (225 -4*3*0) / 2*3
x = [15 +-sq root (225 -4*3*0] / 6
x1 = [15 +15] / 6
x1 = 5
x2 = [15 -15] / 6
x2 = 0
The number is 5
Check
3 * 5^2 = 15 * 5
75 = 75
Answer:
3x^3 - 2x^2 - 15x + 14
Step-by-step explanation:
(3x^2 + 4x - 7)(x - 2) Distribute in the parentheses
3x^3 + 4x^2 - 7x - 6x^2 - 8x + 14 Combine like terms
3x^3 - 2x^2 - 15x + 14 This is the factored expression
