Determine the x-intercepts of the quadratic funtion given in factored form f (x) = 4 (2x-1) (3x+5)

x=1/2, x=-5/3

Step-by-step explanation:

The x intercepts are where y = 0

f (x) = 4 (2x-1) (3x+5)

0 = 4 (2x-1) (3x+5)

Using the zero product property

2x-1 = 0 and 3x+5 = 0

2x-1+1 = 0+1 3x+5-5=0-5

2x=1 3x=-5

2x/2 = 1/2 3x/3 = -5/3

x = 1/2 x = - 5/3
