Question

Help please
Maria is attempting to factor the expression 2xy+24x-7y-84 In her first step, she rewrites the expression as 2x(y+12)+7(-y-12). Which of the following statements is true about Maria's work?

A.
The first step is correct. She should continue to factor the expression.
B.
She factored out a positive GCF in the second group of factors, but it should have been negative.
C.
She factored out a negative GCF in the second group of factors, but it should have been positive.
D.
She factored out a positive GCF in the first group of factors, but it should have been negative.

Answer 1

D. If she factored out a -7, then the expression in parentheses would be (x + 12), matching the first parentheses.

Answer 2

Can you help me with one more ?

Answer 4

can the polynomial below be factored into a perfect square ? if not select the answer that best describes why not
49x^2-70x+25
A. The x^2 coefficient does not permit the factoring
B. The x^2 coefficient does permit the factoring, but the x coefficient does not permit the factoring.

C.
The constant value does not permit the factoring.
D.
The polynomial may be factored into a perfect square.

Answer 5

Did you try to factor it?

Answer 6

YEA i got (7x-5)^2

Answer 7

That's a perfect square. (7x-5) is multiplied by itself
