Answer: 10x + 20
Step-by-step explanation:
10 (x + 2)
Distribute
10x + 20
Ok so your original equation was y=4(x-2)²-1
Therefore we need to expand the bracket to find the original equation.
To do this we need to find (x-2)²=x²-4x+4
Now we multiply this by 4 and subtract 1
4x²-16x+15 Therefore B is the answer
"Roots" (or "radicals") are the "opposite" operation of applying exponents<span>; you can "undo" a power with a radical, and a radical can "undo" a power.</span>
