Question

Find the value of c that makes the expression a perfect square trinomial. x2 + 9 4 x + c

Answer 1

The value of c is 81/64 for the expression a perfect square trinomial.

What is an Expression?

An expression can be defined as a mathematical statement that consists of variables, constants and mathematical operators simultaneously.

It is given that an expression

x² +9/4x +c is a perfect square polynomial

c =?

(a+b)² = a² +2ab+b²

2ab = 9/4

b = 9/8

c = b² = 81/64

Therefore the value of c is 81/64 for the expression a perfect square trinomial.
