Question

Expand the equation (x-5)^2

Answer 1

`x^(2) -10x+25`

Explanation:

1.
`(x-5)^(2)`

2.
`x^(2) -2x*5+5^(2)`

3.
`x^(2) -10x+25`

Answer 2

`x^2 - 10x + 25`

Explanation:

Step 1: Expand the equation

`(x - 5)^2`

`(x - 5)(x - 5)`

Foil

`(x * x) + (x * -5) + (-5 * x) + (-5 * -5)`

`(x^2) + (-5x) + (-5x) + (25)`

Combine

`x^2 - 10x + 25`

Answer:
`x^2 - 10x + 25`
