Question

2x^+5x-1-8x+x^+7-6x+3-3x^​

Answer 1

Answer:

x= -3/2

OR

x = 3

Step-by-step explanation:

given Question:

$2x {}^{2} + 5x - 1 - 8x + x ^{2} + 7 - 6x + 3 - 3x^{2}$

rearranging it we get:

=2x^2 -x^2 -3x^2 +5x -8x -6x -1 +7 +3

= 2x^2 -9x -9

= 2x^2-6x-3x-9 (splitting of middle term)

= 2x (x-3) +3(x-3)

=(x-3) (2x+3)

so, x-3=0

x= 3

Or, 2x+3=0

x= -3/2
