Answer:

x=7,−2

Step-by-step explanation:

Use the quadratic formula to find the solutions.

−b±√b2−4(ac)2a

Substitute the values

a=1, b=−5, and c=−14

into the quadratic formula and solve for

x.5±√(−5)2−4⋅(1−14)2⋅5

Simplify.

x=5±92

The final answer is the combination of both solutions.

x=7,−2
