Factor -7x3 + 21x2 + 3x - 9 by grouping. What is the resulting expression?

irga5000 [103]

Answer:

$(x-3)(-7x^2+3)$ is the resulting expression after grouping

Step-by-step explanation:

Given:

$-7x^3+21x^2+3x-9$

Now taking common $-7x^2$ from 1st 2 numbers and and 3 common from last we get

$-7x^2(x-3)+3(x-3)$

Now taking x-3 common from both numbers we get

$(x-3)(-7x^2+3)$ which is the final equation after grouping
