Question

3x^2 + 17x + 10

Answer 1

u can write it as 3x^2+15x+2x+10
=3x(x+5)+2(x+5)
=?,,,,,, can u do

Answer 2

I'm supposed to factor completely I have no idea how to do that.

Answer 3

ist find the product of cofficients of 1st and last terms = 3 *10 =30
next u find factors for 30 whose sum is 17

30=2 *15
whose sum =2+15=17
so u can split 3x^2 + 17x + 10
as x^2+15x+2x+10
=3x(x+5)+2(x+5)
=(x+5)(3x+2)

Answer 4

Oh okay, thank you.
