Answer 2

Given question -:

subract

$3 {x}^{2} - x + 2 \: from \: 3 {x}^{2} + 5x - 7$

let's try to solve the question

step 1

$3 {x}^{2} + 5x - 7 - (3 {x}^{2} - x + 2)$

step 2

$3 {x}^{2} + 5x - 7 - 3 {x}^{2} + x - 2$

step 3

$3 {x}^{2} - 3 {x}^{2} + 5x + x - 7 - 2$

step 4

$0 + 6x - 9$

step 5

$6 x - 9$

hence the answer is 6x -9
