Question

(x-3)^2+x(x+9) simplify the expression

Answer 1

Explanation:

Simplify.

Include the exponent:

`(x-3)(x-3)+ x(x + 9)={x}^(2) - 6x + 9 + x(x+9)`

Use the Distributive Property:

`{x}^(2) - 6x + 9 + {x}^(2) + 9x`

Add and format the trinomial:

`2{x}^(2) + 3x + 9`

Answer 2

`2x^2 + 3x +9`

Explanation:

`(x-3)^2+x(x+9)`

`(x-3)^2` =
`(x-3)(x-3)`

`(x-3)(x-3)`

`x^2-3x-3x+9`

`x^2-6x+9`

`x(x+9)`

`x^2+9x`

`x^2-6x+9+x^2+9x`

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

`2x^2 + 3x +9`

Hope this helps!
