OpenStudy (imstuck):
Are those "x"'s variables, or do you mean for them to be multiplication signs? Please clarify!
OpenStudy (solomonzelman):
\[10x(6x^2 + 7x + 9)~=~(10 \times 6x^2)+(10 \times7x)+(10 \times9)~=\]\[60x^2+70x+90~.\]
OpenStudy (montesanna99):
It should be 60x^3+70x^2+90x
OpenStudy (anonymous):
yeah, it should be ^3 and not ^2
