Complete the square by adding the correct missing term on the left, then factor as indicated: x2−5x+?=()^2
Added by Joana O.
Step 1
The formula for a perfect square trinomial is (x-a)^2 = x^2 - 2ax + a^2. We can see that the coefficient of x in our equation is -5. This is equal to -2a in the formula. So, we can solve for a: -5 = -2a, a = 5/2 = 2.5. Show more…
