## Answers ( )

Answer:x = – 4, x = 9

Step-by-step explanation:Given

x² – 36 = 5x ( subtract 5x from both sides )

x² – 5x – 36 = 0 ← in standard form

Consider the factors of the constant term (- 36) which sum to give the coefficient of the x- term (- 5)

The factors are – 9 and + 4, since

– 9 × 4 = – 36 and – 9 + 4 = – 5, thus

(x – 9)(x + 4) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = – 4

x – 9 = 0 ⇒ x = 9

Answer:Step-by-step explanation:x ² – 36 = 5x

x²-5x-36=0

a=1 b= -5 c=-36
