MEDAL/FAN4FAN Simplify the product. 5b(6b - 10) A. 11b - 10 B. 5b2 + 6b - 10 C. -b - 10 D. 30b2 - 50b I guessed D, check my answer?
yeap
Help me with more? and thank youuuu
Use the GCF of the terms to write the expression as the product of two factors with integer coefficients. -2x3 - 4x2 + 4x A. x(-2x2 - 4x + 4) B. -2x(x2 + 2x - 2) C. x(-2x2 + 2x - 2) D. -2x(-2x2 + 2x - 2) This one I don't exactly understand, these questions are all review.
where are you stuck?
the very beginning, I learned this stuff years ago and I don't quite remember. I know that GCF means greatest common factor.. but that's about it haha
now, I rewrite your problem like : \[\huge(-2x)x^2 +(2x) (-2x) -(-2x)(2)\] do you understand how I can do it?
I don't know where you're going with this, no.
ok, step: the first term: -2x^3 = -2x *x^2 got it?
okay
the second term: -4x^2 = (-2x)(2x), got it?
yup
and the last one: 4x = (-2)(-2x) , ok?
okay
so the answer is b, right?
yup
thank you!
