Question

Subtract the following:
a) 4z ²xy + x²zy - 5xyz + 2xy²z from x²zy + xyz + xy²z – z²xy
b) 3m² - 2 + 11m from m³ - 9​

Answer 1

Answer:

a) 6xyz-xy²z-5z²xy

b) m³-3m²-7

Step-by-step explanation:

a)

(x²zy+xyz+xy²z-z²xy)-(4z²xy+x²zy-5xyz+2xy²z)

=x²zy+xyz+xy²z-z²xy-4z²xy-x²zy+5xyz-2xy²z

=6xyz-xy²z-5z²xy

b)

(m³-9)-(3m²-2)

=m³-9-3m²+2

=m³-3m²-7
