Solve each quadratic equation by completing the square. give exact answers--no decimals.

The answer is:

First let's identify each term:

So,

Then, we need to add  to each side, resulting:

So:

For the second function we have:

Dividing each side into -3 we have:

Adding to each side, we have:

Then,

Since there is no negative roots in the real numbers, there is no solution for the second equation.

Have a nice day!

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
