Answer:
(x-7)(x-7)
Step-by-step explanation:
this is a perfect square
x^2-14x+49
take the square of the first number,
X^2 = x times x
the sign of the second number
-14x= (-)
the square of the last number
49= 7x7
to check your work you foil it out
(x-7)(x-7)
x times x = X^2
x times -7= -7x
-7 times x = -7x
-7times -7= 49
then combine like terms
x^2-7x-7x+49 = x^2-14x+49
