Question

What’s the answer to this question

Answer 1

Explanation:

`= 2(x - 5) ^(2) + 4(x - 5) + 1`

Now for the first term use the formula :

`{a}^(2) - 2ab + {b}^(2)`

`= 2( {x}^(2) - 10x + 25) + 4(x - 5) + 1`

`= 2 {x}^(2) - 20x + 50 + 4x - 20 + 1`

`= 2 {x}^(2) - 20x + 4x + 50 - 20 + 1`

`= 2 {x}^(2) - 16x + 31`

Answer 2

Your answer will be
2x^2-16x+31 !!
