Multiply the monomial by the binomial and find the value of each for `x=-1, y=0. 25\ a n d\ z=0. 05 :` (i)`15 y^2(2-3x)` (ii) `-3x(y^2+z^2)` (iii)`z^2(x-y)`

Text Solution

Verified by Experts

(i)`15 y^2(2-3x)`
`=30y^2-45xy^2`
`=4.6875`

(ii) `-3x(y^2+z^2)`
`=-6xy^2-3xz^2`
`=0.1875`

(iii)`z^2(x-y)`
`=xz^2-yz^2`
`=-0.0625`
