Tyler solved the following expression: 3 (2 - 2x) - 4x
Step 1: (3)(2)-(3)(2x) - 4x
Step 2: 6. 6 - 4x
Step 3:
- 4x
However Tyler did not have the correct answer. Find Tyler's mistake.
A He multiplied incorrectly in Step 2.
B In Step 2, he forgot bring down the x when he multiplied 3 and 2x.
He added 6 - 6 incorrectly in Step 3.
D In Step 1, he forgot to multiply the 3 by the 4x.

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
