Question

Solve the equation. (r-3)(r+6)=0

Answer 1

Answer:

r^2 = -3

Step-by-step explanation:

Answer 2

Answer:

r = 3 or r = -6

Step-by-step explanation:

Solve for r over the real numbers:

(r - 3) (r + 6) = 0

Split into two equations:

r - 3 = 0 or r + 6 = 0

Add 3 to both sides:

r = 3 or r + 6 = 0

Subtract 6 from both sides:

Answer:  r = 3 or r = -6
