Question

Subtract (-8x^2+2x-9) from ( 5x^2+ 3x+4)​

Answer 1

Answer:

(5x^2 + 3x + 4) - (- 8x^2 + 2x - 9)

=> 5x^2 + 3x + 4 + 8x^2 - 2x + 9

=> 5x^2 + 8x^2 + 3x - 2x + 4 + 9

=> 13x^2 + x + 13

Ans. 13x^2 + x + 13

Hope it helps.

Answer 2

$= 5 {x}^{2} + 3x + 4 - ( - 8 {x}^{2} + 2x - 9)$

$= 5 {x}^{2} + 3x + 4 + 8 {x}^{2} - 2x + 9$

$= 13 {x}^{2} +x + 13$
