1 Step-by-step explanation:K To make the expression a perfect square, wenwed to add to the expression the square of half the coefficient of the x which is 2 Now we have x² + 2x + (2/2)² x² + 2x +1² x²+ 2x + 1, So we need to add 1 to make the expression a perfect square.

Answer 6

25 Step-by-step explanation: Just took on edge.

A = 25 so that the expression is a perfect-square trinomial. Step-by-step explanation: Given : expression We have to find the value of A so that each expression is a perfect-square trinomial. perfect-square is the term in the form of Since , we know the algebraic identity, Given expression is of the form of Thus, comparing , we get, a= x , -2ab = -10x ⇒ b = 5 Thus adding b² term to get perfect-square trinomial. b² = 25 Thus, the perfect-square trinomial becomes So, A = 25

The required correct value is Step-by-step explanation: We are given to find the correct value so that the following expression is a perfect square trinomial : Let the required number be represented by p. Then, we have So, to make the given expression a perfect square trinomial, we must have Thus, the required correct value is

Answer 7

Step-by-step explanation: We have been given an expression . We are asked to convert our given expression into perfect-square trinomial. We know that an equation in form is a perfect square, if To convert our given expression into perfect-square trinomial, we need to add to our given expression. Therefore, our perfect square trianominal would be .
