Please show your work so i can see how you did it
Thanks

Simplify the following polynomials: (Use the ^ symbol to represent exponents)

a) (-2x2 -3x + 7) - (2x3 - 5x + 10)

b) (3x - 7) (4x + 5)

c) (20x2 + 41x - 9) ÷ (5x - 1)

Answer 1

@Luigi0210 & @mathstudent55 can you guys help?

Answer 2

See a)(-2x2 -3x + 7) - (2x3 - 5x + 10)
yoou would first multiply the - (2x3 - 5x + 10)

so you get -2x^3+5x-10

Answer 3

a)-2x^3-2x^2-8x-3
b) 12x^2-13x-35
c) 4x+9

Answer 4

-2x^2 -3x + 7-2x^3+5x-10 then combine like term and you end up with -2x^3-2x^2-8x-3 like princepes said

Answer 5

c) distribute the division sign, then it is (20x^2)/(5x-1) + (41x)/(5x-1) - 9/(5x-1), then simplify.

Answer 6

for b its easier to draw it
