Question

? +16x+64 fill in the missing term making a perfect trinimial square​

Answer 1

Answer:

The missing term in this trinomial term is x^2

let's see how

x^2 + 16x + 64

This can be factorised using identity (a + b)^2

Thus,

(x + 8)^2

If we expand this term we shall get the answer

x2+16x + 64

as - (a + b)^2 = a2 + 2ab + b2

= (x + 8)^2 = x^2 + 2 × x × 8 + (8)^2

Hence we get the answer -

x2 + 16x + 64

Hence the missing term is x2
