Question

Subtract the following polynomials: (7x2 + x + 13) – (2x2 – 5x + 10)

Answer 1

you mean\[(7x^2 + x + 13) – (2x^2 – 5x + 10)\]right?

Answer 2

yes @Voidus

Answer 3

are you dealing with complex numbers yet?

Answer 4

i just dont get how to solve the problem @Voidus

Answer 5

(7x^2 + x + 13) – (2x^2 – 5x + 10)
7x^2 + x + 13 - 2x^2 + 5x - 10
5x^2 + 6x + 3
(-6 +- \(36 - 60)) / 2
(-6 +- \(-24)) / 2
(-6 +- 2i\(6)) / 2
(-3 +- i\(6))

Answer:
5x^2 + 6x + 3
OR
-3 +- i\(6)
