Question

What value of c makes x^2-12x+c a perfect square trinomial

Answer 1

36; Divide b (12) by 2 and square it. 12/2= 6 , 6^2=36

Answer 2

Answer:

the value of C is 36

Step-by-step explanation:

$x^2-12x+c$

find out the value  of 'a' that makes perfect square trinomial. use completing the square method.

In completing the square method, take the coefficient of x and divide it by 2

then square it

coefficient of x is -12

$\frac{-12}{2} =-6$

Now square it $(-6)^2= 36$

the value of C is 36

$x^2-12x+36$

$(x-6)(x-6)=(x-6)^2$

So the value of C is 36
