Find the value of c that makes the expression a perfect square trinomial. then write the expression as the square of a binomial.
x^2+7x+c

For this case we have the following trinomial:

To find the value of c that makes the expression a perfect square, we must complete the square.

We have then:

Rewriting we have:

Therefore the value of c is given by:

Then, the expression written as a binomial is:

the value of c that makes the expression to perfect square trinomial is:

The expression as the square of a binomial is:

equal to

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
