Resolute academy algebra 1

Answer 1

C. 2(x + 10)(x - 10)

Explanation:

2x^2-200\\2(x^2-100)\\2(x+10)(x-10)

Answer 2

B

Explanation:

We can see in the expression that there are 2 x² blocks, 4 -x blocks, and 3 -1 blocks. Therefore, we can write this as

2 * x² + 4 * (-x) + 3 * (-1) = 2x²-4x-3

Comparing this with each answer, we have

A: x²-2x-4 + x² + 2x-1 = 2x²-5. This is not correct

B: 3x²-7x+1-(x²-3x+4) = 3x²-7x+1 -x²+3x-4 = 2x²-4x-3. This seems correct but we can check the other answers to be sure

C: (2x+1)(x-3) = 2x²-6x+x-3 = 2x²-5x-3. This is incorrect

D:
`(8x^(12) - 16x^7 - 12x^6)/(4x^6) = 2x^6 - 4x - 3`. This is incorrect
