What is the factorization of the following trinomial? 15x2 - 44x - 36
BartSMP [9]
15x^2-44x-36

=(15x^2+10x)+(-54x-36)

factor out  5x from 15x^2+10x  = 5x(3x+2)

Factor out -18 from -54x-36 =  -18(3x+2)

=5x(3x+2)-18(3x+2)

Factor out common term (3x+2)

= (3x+2)(5x-18)

hope this helps!

What is the answer for X^3=8/27
maksim [4K]

Answer:

x = 2 /3

Step-by-step explanation:

x^3 = 8/27

Take the cube root of each side

(x^3)^1/3 = (8/27)^1/3

We know that (a/b) ^c = a^c / b^c

x = (8 ) ^1/3 / (27)^1/3

x = 2 /3
