Question

x^2 + 10x + c

Determine the value of c that creates a perfect square trinomial.

A. 16
B. 25
C. 5
D. 10​

Answer 1

Answer:

B)

Step-by-step explanation:

Perfect square trinomial is the expanded form of

${(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab$

So, putting 25 in place of c, we get,

x^2 + 10x + 25

x^2 + 2(x)(5) + 5^2

(x + 5)²
