Answer: 3x2 + 3x - 7
Step-by-step explanation: The first term is, 3x2 its coefficient is 3
The middle term is, +3x its coefficient is 3
The last term, the constant, is -7
1.Multiply the coefficient of the first term by the constant 3 times -7 = -21
2. Find two factors of -21 whose sum equals the coefficient of the middle term, which is 3
Answer:
3x^2 + 3x - 7
Step-by-step explanation:
1. Distribute the - sign to 3x^2 - 7x + 2
(6x^2 - 4x - 5) - 3x^2 + 7x - 2
2. Combine like terms 6x^2 and 3x^2
^ - 4x - 5 + 7x - 2
3. Combine like terms -4x and 7x
3x^2 + - 5 - 2
4. Finally combine like terms -5 and -2
3x^2 + 3x -
So your final answer is 3x^2 + 3x - 7!
I hope this helped :)
