2x + 5 | 6x³ + 7x² - 10x + 25
. . . . . - 6x³ - 15x²
. . . . .. . . . .- 8x² - 10x
. . . . .. . . . . .8x² + 20x

you're the best. thanks everyone! xo

Answer 19

oops
umm... it's
B. \[3x^{2}-4x-5\]
so look
\[3x^{2} \times (2x+5)=6x^{3}+15x^{2}\]
\[-4x \times (2x+5)=-8x^{2}-20x\]
\[-5 \times (2x+5)=-10x-25\]
\[6x^{3}+15x^{2}-8x^{2}-20x-10x-25=6x^{3} + 7x^{2} - 30x - 25\]
