Question

Simplify (2×-9)(×+6)

Answer 1

Answer:

2 x²+3x-54


Explanation:

2x•x+2x•6-9x-9•6

2 x²+12x-9x-54

2 x²+3x-54

Answer 2

For this case we must simplify the following expression:

`(2x-9) (x + 6)`

Applying distributive property that states that:

`(a + b) (c + d) = ac + ad + bc + bd`

We have:

`2x * x + 2x * 6-9 * x-9 * 6 =`

For multiplication of powers of the same base, we place the same base and add the exponents:

`2x ^ 2 + 12x-9x-54 =`

We add similar terms:

`2x ^ 2 + 3x-54`

Answer:

`2x ^ 2 + 3x-54`
