Question

factor completely 2x^3+10x^2+14x+70

Answer 1

well to make it easier find the GCF

Answer 2

the gcf is 2

Answer 3

\[2(x^3+5x^2+7x+45)\] so then we simplify it

Answer 4

woops not 45... I meant 35
\[2(x^3+5x^2+7x+35)\]

Answer 5

thats what I got great thnx

Answer 6

Batameez dil manae na.

Answer 7

Since its a degree 3 polynomial you have to do the rational root test (find the zeros) and so when we do that we are looking for a rational #... http://www.mathportal.org/calculators/polynomials-solvers/polynomial-roots-calculator.php <---- heres a web site that calculates the roots (zeros) so our rational zero is 5

Answer 8

-5 not 5 what the heck

Answer 9

then you plug do \[(x^3+5x^2+7x+35)/(x+5)\]
http://www.mathportal.org/calculators/polynomials-solvers/synthetic-division-calculator.php <----- here it explains how to divide the two

Answer 10

so then you put the two equations together and get \[(x+5)(x^2+7)\]
