Question

(2x+1) (2x+6) - 7(x-2)=4(x+1)(x-1)-9x

ans : - 3/2

help find process

Answer 1

Answer:

-3/2

Step-by-step explanation:

(2x+1)(2x+6) - 7(x-2) = 4(x+1)(x-1) -9x

2x(2x+6) +1(2x+6) -7x +14 = 4x²-4 -9x

4x²+12x+2x+6-7x+14 = 4x²-4 -9x

4x²-4x²+14x-7x+9x+20+4 = 0

16x+24 = 0

16x = -24

x = -24/16

x = -3/2, ans..

Answer 2

Answer:

x=(-3)/2

Step-by-step explanation:

(2x+1)(2x+6)-7(x-2)=4(x+1)(x-1)-9x

2x(2x+6)+1(2x+6)-7(x-2)=4(x²-1)-9x

4x²+12x+2x+6-7x+14=4x²-4-9x

4x²-4x²+12x+2x-7x+9x+6+14+4=0

16x+24=0

16x=(-24)

x=(-24)/16

x=(-3)/2
