Answer 1

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)

and that is the answer

Proper Solution:-

3x2+10x−8

3x2+12x−2x−8

(3x2+12x)(−2x−8)

3x(x+4)−2(x+4)

(3x−2)(x+4

Answer 2

Answer:we can do this by splitting the middle term

Step-by-step explanation:

3x^2-10x-8

=3x^2–12x+2x-8

=3x(x-4)+2(x-4)

=(3x+2)(x-4)

ie x=-2/3 OR 4
