Rewrite the expression (x+3)(3x+8)-3X(x+3)

Mathematics

Multiply (x+3)(3x+8)      x times 3x =3x^2 then multiply x times 8 = 8x
                                 keep multiplying 3 times 3x =9x  then 3 times 8=24 
                          then multiply the -3x(x+3)=  -3x^2-9x
your hole expression will look like this 3x^2+8x+9x+ 24-3x^2-9x

if you need to simplify you can do by adding or subtracting them.
for example you can add 8x+9x= 17x

IRINA_888 [86]
Simply solve for x:
-x^2 + 9 = 0 => x = 3 and x = -3;

plug x = 3 and x = -3 into the original equation you get 3 = 3 and -9 = -9, respectively;
So, the two intersecting points are (-3, -9), (3, 3).
And of course, the parabola opens down since its square term is minus.
