It is: 12(2x+3) when factored
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).
7x2+49x+84 = 0 Divide all terms by 7: x2+7x+12 = 0 Factorize: (x+3)(x+4) = 0 Therefore the x intercepts are -3 and -4
The answer is 120. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
17 + 13 + 12 + 12 + 6 + 9 = 69.
