1÷2(2x+6)=4x-1

solve pls no links!!!​

Step-by-step explanation:

1 ÷ 2(2x+6) = 4x-1

1 = (4x - 1)(4x + 12)

Use FOIL method.

1 = 4x * 4x  + 4x *12 - 1 * 4x - 1*12

1 = 16x² + 48x - 4x - 12

1 = 16x² + 44x -12

0 = 16x² + 44x - 12

16x² + 44x - 12 = 0

Divide the whole equation by 4

4x² + 11x - 3 = 0

4x² + 12x - 1x -3 = 0

4x(x + 3) - (x + 3) = 0

(x + 3)(4x - 1) = 0

x + 3 = 0          ; 4x -1 = 0

    x = -3           ; 4x   = 1

                            x = 1/4

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
