Solve the equation.

(4n + 5)(3n - 7) = 0

(5/4), (7/3)

(-5/4), (7/3)

(5/4), (-7/3)

(-5/4), (-7/3)

You can set each equation to 0 so it would look like this:
And solve

4n+5=0. 3n-7=0
-5=-5. +7=+7

4n = 5. 3n = 7
4n/4 = 5/4. 3n/3 = 7/3
n = 5/4 n = 7/3

The first set of answers are the correct answers for n.

Ok, so if you have xy=0, then assume that x and y are equal to 0
so we have
(4n+5)(3n-7)=0
assue that
4n+5=0 and 3n-7=0

solve those
4n+5=0
minus 5
4n=-5
divide by 4
n=-5/4

3n-7=0
add 7
3n=7
divide 3
n=7/3

-5/4 and 7/3

2nd option

I’m not sure i’m sorry
