Write and equivalent expression for the following expression: ab

ab = a(b)

Step-by-step explanation:

cuz u can just add parentheses

1) -19x-14

2) x=0, x=3

Step-by-step explanation:

1) (3x+2)(x-7)

Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.

- 21x + 2x -14

Combine like terms

- 19x - 14

2)

In order to find the factors of x, set the expression equal to 0.

- 9x = 0

Factor out the highest common multiple (3x)

3x(x-3) = 0

In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3

Or 3x = 0 -> x = 0

Hope this helps!
