Question

What will be (4x-2)(2x+1)=3x+4

Answer 1

Answer:

(4x-2)(2x+1)=3x+4

4x(2x+1)-2(2x+1)=3x+4

8x^2+4x-4x-2=3x+4

8x^2-2-4=3x

8x^2-6=3x

8x^2-6-3x=0

8x^2-3x-6=0

8x^2-8x+6x-6=0

8x(x-1)+6(x-1)=0

(8x+6)(x-1)=0

(8x+6)=0

x=-6/8=-3/4

(x-1)=0

x=1

Answer 2

Answer:

$= > (4x - 2)(2x + 1) = 3x + 4 \\ = > 8x {}^{2} + 4x - 4x - 2 = 3x + 4 \\ = > 8x {}^{2} - 2 = 3x + 4 \\ = > 8x {}^{2} - 3x - 2 - 4 = 0 \\ = > 8x {}^{2} - 3x - 6 = 0$
