Explanation:
#"to find the zeros set "f(x)=0#
#(3x-5)(2x+7)=0#
#"equate each factor to zero and solve for x"#
#2x+7=0rArrx=-7/2#
#3x-5=0rArrx=5/3#

Explanation:
Zeros, Roots and Solutions to a polynomial are all the same thing, to find the zeros we first set
The zero product rule states that if:

f(x)=0 when
Explanation:
You just have to see how f(x) can be 0. In this expression f(x) = 0 when either of the parentheses is 0, i.e. either
(3x-5)=0
or (2x+7)=0
(3x-5)=0 when 3x=5 or
(2x+7)=0 when 2x=-7 or
