Subtracting Polynomials
(this is subtracting polynomials for more info)
1) 65ab + 49b(exponent 2)(p.s. don't know how to make exponents lol) -75a(exponent 3)
- 49ab - 37b(exponent 2) +43a(exponent 3)
=?
2) 23a + 76b - 42c
- 13a - 34b + 18c
=?
3) 24p - 39q + 17r
- -17p - 26r
=?
4) 46k - m + 18n
- 59k + 18m + 43n
=?
5) 8x(exponent 2)y(exponent 4) - 18x(exponent 3)y(exponent 5) + 96x(exponent 4)y(exponent 6
- 25x(exponent 2)y(exponent 4) - 36x(exponent 3)y(exponent 5) - 156x(expo 4)y(expo 6)
=?
plz i need it as soon as possible ty
