Answer:
[tex]5(4x-5)(4x+5)[/tex]
Step-by-step explanation:
[tex]80x^2-125= \\\\5(16x^2-25)= \\\\5(4x-5)(4x+5)[/tex]
Hope this helps!
5( 4x-5)(4x+5)
80x^2 – 125
Factor out a 5
5( 16 x^2 - 25)
Inside the parentheses is the difference of squares
5 ( (4x)^2 - 5^2)
We know the difference of squares is (a^2 - b^2) = (a-b) (a+b)
