Question

$5.subtract \\ (c) (- 2x2 + 4x - 4)from(2 - 4x -x2)$
​

Answer 1

HERE IS YOUR ANSWER MATE.....;

$eq {}^{n} (1.) = > - 2x {}^{2} + 4x - 4$

$= > - x {}^{2} + 2x - 2$

$eq {}^{n} (2.) = > - x {}^{2} - 4x + 2$

IF WE SUBTRACT 2-1 WE GET

$= > - 6x = - 4$

$= > x = \frac{2}{3}$

HOPE ITS HELPFUL.....:-)

Answer 2

$Subtract \: (2 {x}^{2} + 4x - 4) \: from \: (2 - 4x - {x}^{2} ) \\ ( - {x}^{2} - 4x + 2) - (2 {x}^{2} + 4x - 4) \\ - {x}^{2} - 4x + 2 - 2 {x}^{2} - 4 x + 4 \\ - 3 {x}^{2} - 8x + 6 \\ - (3 {x}^{2} + 8x - 6)$
