Answer:
{- 11, - 1 }
Step-by-step explanation:
Since the coefficient of the x² term is 1 , to complete the square
add (half the coefficient of the x-term )² to both sides
x² + 2(6)x + 36 = - 11 + 36 ← complete the square on the left side
(x + 6)² = 25 ( take the square root of both sides
= ± 
x + 6 = ± 5 ( subtract 6 from both sides )
x = - 6 ± 5
x = - 6 + 5 = - 1 or x = - 6 - 5 = - 11
Answer:
(2x^3-2x^2-12x) is the required product.
Step-by-step explanation:
The given equation is:
2x(x-3)(x+2)
Solving the above given equation, we get
=(2x^2-6x)(x+2)
which can be written as:
=(2x^3-6x^2+4x^2-12x)
Solving the like terms, we get
=(2x^3-2x^2-12x)
which is the required product of the given expression.
