Question

uhm anyone wanna give it a go?

Answer 1

Both B and C are correct.

Answer 2

Remember that when you square a negative (namely the -5), it becomes positive, so both the 5 and the -5 are the answers.

Answer 3

if you have x²- a constant
if the constant is a square number then this falls into a difference of two squares

difference of two squares is
(x+y)(x-y)
because it cancels out to be x²-y²

Answer 4

constant does not have to be a square number it is just easier to explain that way
