Question

Need help factoring polynomials

5t^3 - 21t^2 + 18t

Answer 1

t(5t-6)(t-3)

Answer 2

first take outt ;
= t(5t^2 - 21t + 18)

now you need to use factors of 18 and also 5 to figure out how to get 18 as a product and also to add to get -21

it will be like
(5x )(x )

-6 and -3 will fit the bill
so we get
t(5t - 6)(t - 3)

Answer 3

thanks for the explanation, question, does this mean the polynomial is not prime???

Answer 4

yes - if its prime it would not factor

Answer 5

i get it thanks, the 5 threw me off.

Answer 6

ok - yw

- yea its a bit more complicated when you have a number before the x^2
