The factored form of a quadratic expression is (3x - 4) (x + 5). What are the x-intercepts of the related quadratic function?

3/4 and - 5

4/3 and - 5

-3/4 and 5

-4/3 and 5

In this question, we're trying to find the x intercepts from the given quadratic expression.

To find the x intercepts, solve for x:

(3x - 4) (x + 5)

(3x - 4):

3x - 4 = 0

add 4 to both sides

3x = 4

divide both sides by 3

x = 4/3

(x + 5):

x + 5 = 0

subtract 5 from both sides

x = - 5

This means that the x intercepts are 4/3 and - 5

Answer:

4/3 and - 5
