Thanks tons!
This is a "difference of squares" problem and factors nicely into
(a-4)(a+4)
If you want to solve then you set this equal to zero and,
a-4 = 0
a = 4
a+4 = 0
a = -4
Have a good day!
( a - 4 ) ( a + 4 )
(a - 4)(a + 4)
(a+4)(a-4) - the difference of perfect squares. Multiply it out and see what happens.
(a-4)(a+4)=0
its a difference of squares.
(a + b)(a â b) = a² â b²
(a-16)*a
