Answer:
The options 2x² + x² + x = 30 and 9x + 3x² = 14 + x + 1, and -x² + 4x + 7 = - x² - 9
Step-by-step explanation:
After being rearranged and simplified, which of the following equations could be solved using the quadratic formula?
The answers are:
2x² + x² + x = 30
9x + 3x² = 14 + x + 1
-x² + 4x + 7 = - x² - 9
Step-by-step explanation:
(12)(2) = 24 Find 2 numbers whose product is 24 and whose sum is 11 (8 and 3 work)
Rewrite 11x as 8x+3x and factor by grouping:
12x2 + 8x + 3x + 2 = 0
4x(3x+2) + 1(3x+2) = 0
(3x+2)(4x+1) = 0
x = -2/3 or x = -1/4
