ANSWER

x^2-4x-21

EXPLAIN

First expand the brackets by multiplying the number from the first bracket to the second bracket

you will get this = x^2 + 3x- 7x- 21 ,then u collect the like terms which is (3x & -7x).

your answer ( x^2 - 4x - 21 ).

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
