Question

factor the trinomial completely ........25x^3-55x^2-60x

Answer 1

Step one: take out the common factor (5). Step two: Use the ac method to finish factoring. Looking for a pair of factors of -60 that have a difference of -11 might lead you to -15 and 4.

Answer 2

ok I get that part now.. I see how -15 and for would =11 when added and when multiplied it's 60

Answer 3

-15 and 4 sorry

Answer 4

\[25x^3-55x^2-60x=5x(5x^2-11x-12)\]\[5x(5x^2-15x+4x-12)=5x(5x(x-3)+4(x-3))\]\[=5x(5x+4)(x-3)\]
