# Solving Quadratic Equations with Square Roots

## Exercise 1.13 - Solution

a
Since is alone on the left hand side we will square root both the sides.

The equation therefore has two solutions. Answering exactly we get and and with two decimal places, and

b

Here, we must divide by before we square root both sides. We must remember that we get two solutions.

c

We must use inverse operations to get the -term alone.

d
Here we must begin the solution by using inverse operations to get the -term alone.
