Question

How do you simplify `(4x^2 -11x + 10) + (5x - 31)`?

Answer 1

`4x^2-6x-21`

Explanation:

Begin by writing the expression without the brackets. Since there is no numeric value written outside the bracket we can assume there is a 1.

That is `1(4x^2-11x+10)+1(5x-31)`

Hence `to4x^2-11x+10+5x-31`

now `color(blue)"collect like terms"`

`color(red)(4x^2)color(magenta)(-11x+5x)color(blue)(+10-31)=4x^2-6x-21`
