Hello from MrBillDoesMath!
Answer:
"The factoring should follow the perfect square trinomial pattern"
Discussion:
y^2 - 2(y)(3) + 3^2 =
(y -3
) ^2
not (y-3) (y+3) so the last step shown is incorrect. The answer is "The factoring should follow the perfect square trinomial pattern"
Thank you,
MrB
to write decimal as a percent, multiply by 100
so 0.78 *100 = 78%
< makes it a true statement
