Question

fill the missing term for making a perfect trinomial square _ + 16x +64

Answer 1

Hola

Here is your 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

$<b>x2</b>+16x + 64$

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


Hope it helps
