Clara found the product of 3 – 6y2 and y2 + 2. her work is shown below.
(3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2)
= 3y2 – 12y2
= –9y2
is the student’s work correct?
no, she did not multiply –6y2 by 2 correctly.
no, she did not add 3y2 and –12y2 correctly.
no, she did not use the distributive property correctly.
