Question

Substract

a. –3m2 – 6m + 3 from 5m2 – 9

b. 4x3 – 7x2 + 5x – 4 from 6 – 5x + 6x2 – 8x3​

Answer 1

Step-by-step explanation:

5 m^2 --9+3m^2+6m -3=8m^+6m -9

Answer 2

Answer:

a. 5m²-9-(-3m²-6m)

-> 5m²-9+3m²+6m

-> 8m²+6m-9

b. 6-5x+6x²-8x³-(4x³-7x²+5x-4)

->6-5x+6x²-8x³-4x³+7x²-5x+4

->-12x³+13x²-10x+10
