Question

here is a hard one
factor 45s^2+100st+55t^2

Answer 1

polynomials need to factor please help?

Answer 2

start with taking out 5 as a common factor

\[5(9s^2 + 20st + 11t^2)\]

Answer 3

so then the factoring becomes

\[5(9s + 11t)(s + t)\]

Answer 4

are there anymore steps to take after?
