Question

Find the value of c that makes the trinomial a perfect square. . x² – 24x7c

Answer 1

Answer:

144

Step-by-step explanation:

The equation to find c is:

$(\frac{b}{2} )^{2}$

So put -24 into b:

$(\frac{-24}{2} )^{2}$

Which simplifies to:

144

So if you want to test this:

x^2 - 24x + 144

is

(x-12)^2
