-3x(x+7)
can you show me how you got the answer
sure. Basically you factor out the common factor from both coefficients, which are -3. Then take out the common variable, which is x. You are left with -3x(x+7)
\[-15x^2-21x\]You can factor -3x out of the expression. But the answer @some1 gave is incorrect. It should be:\[-3x(5x+7)\]
yea that's right. sorry bout that.
