Find the value of c that makes the expression a perfect square trinomial.
then write the expression as a square of a binomial.

i dont really understand these instructions can someone solve a problem using these examples? heres one of my problems: x^2+3.6x+c

c = 3.24

(x+1.8)²

Step-by-step explanation:

The question wants you to fill in the last term.

To find the last term, you must use the formula (b/2)^2.

Let's use this formula for the equation you gave: x²+3.6x+c

c = (b/2)²

c = (3.6/2)²

c = 3.24

That is the value of c.

Let's plug in c in the last term for better understanding.

x²+3.6x+3.24 is now factorable.

The factored form will turn out to be : (x+1.8)²

what is the graph

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
