Question

4a^2-16a+16

Answer 1

@CAT2142276 do you know the expansion of \((a-b)^2\)?

Answer 2

isnt it (a-b) (a+b)?

Answer 3

That's \((a^2-b^2)\) we used it in the previous question!!
Try to expand and tell me

Answer 4

its
\[ax^{2}+bx+c\]

Answer 5

Nope @CAT2142276 (a-b)^2 doesn't have a x
I'll give you a hint, multiply and simplify this
\[(a-b) \times (a-b)\]
