Question

find all zeros.
f(x)=(2x-1)(x-5)

Answer 1

need help

Answer 2

x=-5 will make the second term zero (and thus the function zero). The first term we set equal to zero and solve:
2x-1=0 thus,
x=1/2 will make the function zero as well. The solutions are x=1/2, x=-5

Answer 3

oooops meant x=5 not -5

Answer 4

could you make each step?

Answer 5

ah I see

Answer 6

so you use 2x-1=0 and x-5= 0 right?
