HEY MATE! HERE'S YOUR ANSWER!
p(x) = (x+2)(x+3)
p(x) = x(x+3)+2(x+3)
p(x) = x² + 3x + 2x + 6
p(x) = x² + 5x + 6 ....(i)
Now,
here, 3 and 2 are the zero of the polynomial.
as, x+2 = 0
=> x = -2
and, x+3 = 0
=> x = -3
then,
p(-2) = (-2)² + 5(-2) + 6
p(-2) = 4 - 10 + 6
p(-2) = 10-10
p(-2) = 0 ...... ANSWER.
Also,
p(-3) = (-3)² + 5(-3) + 6
p(-3) = 9 - 15 + 6
p(-3) = 15-15
p(-3) = 0 .....ANSWER.
HOPE IT WAS HELPFUL ✌️!

p(x)=x(x+3)+2(x+3)
p(x)= 2x+3x+2x+6
p(x)=7x+6
p(x)-7x=6
p×(-6x)=6
-6xp=6
xp=6/-6
xp=-1
p(x)= 2x+3x+2x+6
p(x)=7x+6
p(x)-7x=6
p×(-6x)=6
-6xp=6
xp=6/-6
xp=-1
