Question

Enter the correct value so that each expression is a perfect-square trinomial.

x2 – 10x +

​

Answer 1

2x-10x+
It’s answer is 25

Answer 2

`x^2-10x+25`

Explanation:

We have been given an expression
`x^2-10x+`. We are asked to convert our given expression into perfect-square trinomial.

We know that an equation in form
`x^2+bx+c` is a perfect square, if
`c=((b)/(2))^2`

To convert our given expression into perfect-square trinomial, we need to add
`((10)/(2))^2` to our given expression.

`((10)/(2))^2=5^2=25`

Therefore, our perfect square trianominal would be
`x^2-10x+25`.
