Answer: 330

Step-by-step explanation: First plugg in 7 for the x. The equation would look like 6(7^2) + 4(7) + 8. Then you would simplify the 7's. 6(49) + 28 + 8. Put like terms together by combining 28 and 8. 294 + 36. That would equal 330.

harina [27]

When using factoring by grouping, the replacement terms will both have the same sign of the original middle term. If the last term is negative, then the signs of the factors will have one of each sign with the “stronger” number (the larger absolute value) matching the middle term. hope this helps
