What’s D it doesn’t show?
Answer:
c³ + cd³ + 3c²d + 3cd²
Step-by-step explanation:
(c+d)^3 is worded as <em>c plus d quantity cubed</em> which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.
(c+d)(c+d)(c+d)
<em>You can only multiply 2 at a time so do the first two then the result and the third one.</em>
<em>Distribute everything in one quantity to the other so </em><em>c*c = c^2 and c*d = cd</em>
= (c^2 + 2cd + d^2)(c+d)
= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3
<em>Combine like terms</em>
= c³ + 3c²d + 3cd² + cd³
Answer:
use calcES to get d zeros of the polynomial without any stress
32/10 is not a whole number because when you turn it into a mixed number, it will be 3 2/10. Whole numbers can only be like 1,2,3,4
