Find the value of c that makes each trinomial a perfect square<br> x^2-19x+c<br> Please Help! :)
tensa zangetsu [6.8K]

The value of c is \frac{361}{4}

Explanation:

Given that the trinomial is x^2-19x+c

We need to determine the value of c such that the trinomial is a perfect square.

The value of c can be determined using the formula,

c=(\frac{b}{2})^2

From the trinomial, the value of b is given by

b=-19

Substituting the value of b in the above formula, we have,

c=(\frac{-19}{2} )^2

Squaring both the numerator and denominator, we have,

c=\frac{361}{4}

Thus, the value of c is \frac{361}{4} which makes the trinomial a perfect square.
