P(p-q) - q(q-p)

a(b+c) = a(b) + a(c) so...

p(p) + p(-q) - q(q) - q(-p)

p² -pq - q² + qp

a*b = b*a so...

-pq + qp = 0 so...

The answer is...

p² - q²

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>
