WORTH 20 POINTS FIRST ANSWER IS MARKED BRAINLIEST. Im confuzzled. we are doing polynomials in class, but I don't get them without a teacher explaining it on the board. This quarantine thing has brought my grades down, and i REALLY need help.

The answer to your question is There are four terms in the product

                                                     The product is degree 2.

Step-by-step explanation:

Product               (-d + e)(4e + d)

Process

1.- Multiply "-d" by the two terms of the second parentheses

- (-d)(4e) = -4de              You have to multiply the signs, then the numbers and

                                       finally the letters.

- (-d)(d) = -d²

2.- Multiply "e" by the two terms of the second parentheses

-(e)(4e) = 4e²

-(e)(d) = ed

3.- Write all the results together

             -4de - d² + 4e² + ed

-Simplify like terms

              4e² -3de - d²
