What value of B makes the expression. x² + Bx + 81 a perfect square trinomial?

Oxana [17]

Answer:

B.) 18

Step-by-step explanation:

To find the correct b value we use this formula

b² - 4ac = 0

b = What we are solving for

a = 1

c = 81

b² - 4(1)(81) = 0

b² - 324 = 0

b² = 324

$b = \sqrt{324}$

b = ±18

And 18 is one of the answer choices

So B.) 18 is the correct answer.
