What values are needed to make expression a perfect square trinomial?

Perfect Square Trinomial Formula An expression is said to a perfect square trinomial if it takes the form ax2 + bx + c and satisfies the condition b2 = 4ac. The perfect square formula takes the following forms: (ax)2 + 2abx + b2 = (ax + b) (ax)2 −2abx + b2 = (ax−b)

Which value must be added to the expression x 2 x?

Answer: We need to add 1/4 to the expression x2 + x to make it a perfect square.

Which value must be added to the expression x 2 16x to make it a perfect square trinomial?

64
