2r + 9 = 7 - 3r

Subtract 9 from each side:

2r = -2 - 3r


Add 3r to each side:

5r = -2

Divide both sides by 5:

r - -2/5

Solve the quadratic equation for x. What is the product when the roots are multiplied? (x + 2)2 = 1
tekilochka [14]

Regroup terms

2(x + 2) = 1

Divided both sides by 2

x + 2 = 1/2

Subtract 2 from both sides

x = 1/2 - 2

Simplify 1/2 - 2 to -3/2

<u>x = -3/2</u>
