Harry is trying to solve the equation y = 2x2 − x − 6 using the quadratic formula. He has made an error in one of the steps below. Find the step where Harry went wrong. (1 point)
Step 1: x equals the negative of negative 1 plus or minus the square root of the quantity negative one squared minus 4 times 2 times negative six, end quantity, all over 2 times 2.
Step 2: x equals the negative of negative 1 plus or minus the square root of negative one plus forty-eight all over two times 2.
Step 3: x equals the negative of negative 1 plus or minus the square root of forty-seven all over two times 2.
Step 4: x equals 1 plus or minus the square root of forty-seven all over 4.

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β
