9x^2-16y^2=
(3x+4y)(3x-4y)
Answer:
x=-5 or x=3
Step-by-step explanation:
when multiplying anything by 0, the answer will be zero
In this case, one of the two factors has to be equal to 0
start by splitting into
(x+5) = 0
solve the equation
subtract 5 from both sides
x = -5
now, repeat for the other binomial
x-3 = 0
add 3 to both sides
x=3
