Answer:
±√177/2+11/2
Step-by-step explanation:
Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square. Exact Form:x=±√177/2+11/2
x=12.15206734…,−1.15206734…
30.25
Quadratic Equation: x² - 11x - 14 = 0
Number added = (b/2)² = (-11/2)² = 30.25
Solving Steps:
[add both sides by 30.25]
[complete square]
[exchange sides]
