Question

Substract the sum of 2 x-x² +5 and - 4x-3+7x²
from 5.​

Answer 1

Answer:

$- {6x}^{2} + 2x + 13$

Step-by-step explanation:

$2x - {x}^{2} + 5 + ( - 4x - 3 + {7x}^{2} )$

$- 2x + {6x}^{2} + 2$

subtraction from 5

$5 - ( - 2x + {6x}^{2} + 2)$

$5 + 2x + 5 - {6x}^{2} + 5 - 2$

$5 + 5 + 5 - 2 + 2x - {6x}^{2}$

$13 + 2x - {6x}^{2}$

$- {6x}^{2} + 2x + 13$
