To factorize the quadratic expression x^2 + 7x + 12, we need to determine two numbers that multiply to give us 12 and add up to 7. In this case, the numbers are 3 and 4. Therefore, the factored form of the expression is (x + 3)(x + 4).
=3x * * * * * The correct answer is: x2 + 7x + 12 = (x + 3)(x + 4).
x2-7x+12 (x-3)(x-4)
x^2 +7x+12 = (x+3)(x+4) when factored
(x + 10)(x - 3)
(x - y + 7)(x + y)
