Mathematics

1 answer:

Rudik [331]3 years ago

4 0

Answer:

x = 4 or x = -3

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - x - 12 = 0

The left hand side factors into a product with two terms:

(x - 4) (x + 3) = 0

Split into two equations:

x - 4 = 0 or x + 3 = 0

Add 4 to both sides:

x = 4 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = 4 or x = -3
