Question

Multiply the following binomials and verify th
(i) (2x - 5y) (5x + 2y2); x = 2, y = -1
1 1
at - b
4 5
ba
; a = 8, b= 5
(ii) (m + n) (2m - 3n); m = -2, n = 0
(iv) (0.1p + 0.2q) (0.29 - 0.1p); p = 10, q = 5
Simplify the following:
210 (YY) + (x + 2y) (x - y)​

Answer 1

Aɴsᴡᴇʀ:-

If ,

x = 2

ʏ = -1

Then,

( 2x - 5y ) ( 5x + 2y² )

= ( 2 ( 2 ) - 5 ( -1 ) ) ( 5 ( 2 ) + 2 ( -1 )²)

= ( 4 + 5 ) ( 10 + 2 )

= 9 + 12

= $\LARGE{\boxed{\sf{\pink{ 21 }}}}$
