Question

Which of the following is the correct factored form of the given equation?

x2 + 3x - 4 = 0
(x - 1)(x + 4) = 0
(x - 1)(x - 4) = 0
(x + 1)(x - 4) = 0

Answer 1

Explanation:

(X-1)(x+4)=o

Answer 2

The factored form of a polynomial is comprised of factors in which the sum is equal to the coefficient of the second term and the product is equal to the coefficient of the third term. In this case, the factors of x2 + 3x - 4 = 0 are 4 and -1. hence the answer is B. (x - 1)(x - 4) = 0
