Factor the following polynomials:
4m^2-4mp+p^2
16s+56s+49
16c^2+72cd+81d^2
How can you determine is a quadratic expression is a perfect square trinomial?
TY
(a+b)^2 = a^2 + 2ab + b^2
You need the first and last terms to be perfect squares, and the middle term to be twice their product.
4m^2-4mp+p^2 = (2m-p)^2
16s^2+56s+49 = (4s+7)^2
16c^2+72cd+81d^2 = (4c+9d)^2
