How do you solve the quadratic equation 7x2-5x equals 0 by factoring?

Answer 1

if the x in "7x2" is variable x, then

7x(2)-5x=0

14x-5x=0

9x=0

x=0

if the x in "7x2" is a symbol for multiplication, then

7(2)-5x=0

14-5x=0

-5x= -14

5x=14

x= 14/5

x= 2 4/5

or, to factor it out...

x(14-5)=0

x(9)=0

9x=0
