Question

from the sum of 4+3x and 5-4x + 2x square,subtract the sum of 3x square-5x and -x square+ 2x+5​

Answer 1

Answer:

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

Answer 2

Answer:

2x+4=2(x+4)

Step-by-step explanation:

sum of 4+3x and 5-4x + 2x square, we get

4+3x+5-4x+2x^2=2x^2-x+9----eqn1

sum of 3x square-5x and -x square+ 2x+5, we get

3x^2-5x-x^2+2x+5=2x^2-3x+5----eqn2

eqn1-eqn2, we get

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