Question

solve plzzzzzzzzz....

Answer 1

p(x) =x²+12x+20
p(x)=x²+(10+2)x+20
p(x)=x²+10x+2x+20
p(x)=x(x+10)+2(x+10)
p(x)=(x+10)(x+2)
x=-10, - 2
Hey mate above is ur answer hope it helps you.......

Answer 2

x²+12x+20
10 x 2=20
10 + 2=12
x²+10x+2x+20
Group them
(x²+10x) + (2x+20)
Take the common out;
x(x+10) + 2(x+10)
(x+2)(x+10)
If you want to find x;
x=-10,-2
