Zeros of f(x)=4(x+7)2(x7)2 are 7 and 7.

Explanation:

If f(x)=u(xa)m(xb)n(xc)p(xd)q, a multiplication of number of binomials of degree one, then zeros of polynomials are a, b, c and d, as any of them when put in place of x will make f(x)=0. Here u is just a constant.

Hence, zeros of f(x)=4(x+7)2(x7)2 are 7 and 7.
