Answer:
Kyle did not solve the question correctly
Step-by-step explanation:
The equation (-4x +9)^2 is a perfect square trinomial.
A typical example of a perfect square trinomial is (x +y) ^2 = x^2 + 2xy + y^2
Therefore, (-4x + 9)
= (-4x)^2 + 2(-4x)(9) + (9)^2
= 16x^2 + 2(-36x) + 81
= 16x^2 - 72x +81
The result Kyle gave was 16x^2 + 81. This is incorrect.
Therefore, Kyle did not solve the question correctly
Answer:
20 and 2020
Step-by-step explanation:
i got it right on edge
