Answer:

a.    (x+2)(x+3)

b.   x = -2

     x = -3

Step-by-step explanation:

a.

split 5x into 2x + 3x

then, you get

x² + 2x + 3x + 6

Split into (x² + 2x) + (3x + 6)

factorize individual groups

x (x + 2) + 3 (x + 2)

combine x + 3

your final answer is

(x + 2) (x + 3)

b.

if (x + 2) (x + 3) = 0

then (x+2) = 0 and (x+3) = 0

x + 2 = 0

x = -2

x + 3 = 0

x = -3
