Answer:
<em>Option C. is the correct option.</em>
<em />
Step-by-step explanation:
<em>Clara found the product of (3 - 6y²) and (y² + 2) and she did it as below</em>
<em />
<em>(3 - 6y²)(y² + 2) = 3(y²) + (-6y²)×2 = 3y² - 12y² = -9y²</em>
<em />
<em>She did the step wrong as highlighted above. She did not use the distributive property correctly.</em>
<em />
<em>Now we will do it in a correct way.</em>
<em />
<em>(3 - 6y²)(y²+2) = 3(y² + 2) - 6y²(y² + 2)</em>
<em />
<em>= 3y^{2}+6-6y^{4}-12y^{2}=-6y^{4}-9y^{2}+6</em>
<em />
<em>Therefore Option C. is the correct answer.</em>
<em>Hope it helps:)</em>
