Find the following products: (i)(z+3/4)...

Find the following products: (i)`(z+3/4)(z+4/3)` (ii) `(x^2+4)(x^2+9)` (iii)`(y^2+12)(y^2+6)` (iv) `(p^2+16)(p^2-1/4)`

Text Solution

Verified by Experts

Given:
`(1) (z+3/4)(z+4/3)`
`=> z(z+4/3)+3/4(z+4/3)`
`=> z^2+4/3z+3/4z+1`
`=> z^2+25/12z+1`
(2) `(x^2+4)(x^2+9)`
`=>x^2(x^2+9)+4(x^2+9)`
`=> x^4+9x^2+4x^2+36`
