Question

Solve the equation by factoring or completing the square: x^2+4x+3=0

Answer 1

(x-4)(x-1) is the factor and then solve for x which is x=4 and x= 1

Answer 2

Factor x^2 + 4x + 3

(x + 1)(x + 3) = 0

Solve for x

Ask, when will (x + 1)(x + 3) equal zero?

When x + 1 = 0 or x + 3 = 0

Solve each of the two equations above

Answer: x = -1, -3
