Question

Perform the indicated operation.Subtract (4x^2-5) from the sum of (x^2 - 5x + 1) and (3x^2 – 3x+4)The answer is

Answer 1

We have the sum of

`\mleft(x^2-5x+1\mright)+(3x^2-3x+4)`

we sum similar terms

`4x^2-8x+5`

then we subtract (4x^2-5) from the result of the sum above

`(4x^2-8x+5)-\mleft(4x^2-5\mright)=4x^2-8x+5-4x^2+10`

then we sum similar terms, and we find the answer

`-8x+10`
