What are the factors of 3x2 + 10x + 8? (3x+8)(x+1)
(3x+1)(x+8)
(3x+2)(x+4)
(3x+4)(x+2)

(3x+2)(x+4)

Step-by-step explanation:Explanation:

3x2+10x−8

first multiply

3

with −8

and we get −24

then find two numbers that if we add or subtract we get

+10

and if we multiply we get

−24

and the numbers are

+12

and

−2

then we place those numbers as follow :-

3x2+12x−2x−8

then we group them

(3x2+12x)(−2x−8)

now take the common factor out.3x(x+4)−2(x+4)

then group the numbers outside of the brackets

(3x−2)(x+4)

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees
