What value for c will make the expression a perfect square trinomial? x2 – 7x + c

ANEK [815]

Answer:

Final answer is $\frac{49}{4}$ .

Step-by-step explanation:

Given expression is $x^2-7x+c$ .

Now we need to find about what value for c will make the given expression $x^2-7x+c$ , a perfect square trinominal.

Coefficient of middle term that contains x, in $x^2-7x+c$ -7.

Take half of that so we get $-\frac{7}{2}$ .

Then take square of the half value.

We get $\left(-\frac{7}{2}\right)^2=\frac{49}{4}$ .

We add the square value to make perfect square trinomial.

Hence final answer is $\frac{49}{4}$ .
