-4t^2 + 64


-(4t^2 - 64)


-( (2t)^2 - 8^2)


-(2t-8)(2t+8) ... use the difference of squares formula here


So the expression factors to -(2t-8)(2t+8)

Factor completely. Remember to look first for a common factor. If a polynomial is prime, state this.
72.
−4t^2 + 64

-+4t%5E2+%2B+64

-+4%28t%5E2+-+16%29 ---- Factoring out HCF, - 4
