Find c

The question is incomplete. However, I'll assume the expression is a perfect square.

To find c, we make use of the following formula

Where

By comparison with

So, becomes

The value of c that makes the expression, a perfect square is 4 and the expression is:

45

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
