Question

1. Find the product of the following binomials.

(i) (5x + 3) (2x + 4)
(iv) (m²n - 5) (6 - mn²)
(v) (4x2 + 7y3) (3x - 2y).
(vi) (1.1x + 2.7y) (1.1x-2.7y)​

Answer 1

Answer:

Okay dear pls wait....

i) (5x + 3) (2x + 4)

5x( 2x + 4 ) + 3( 2x + 4)

10x² + 20x + 6x + 12

= 10x² + 26x + 12

iv) (m²n – 5) ( 6 – mn²)

m²n( 6 – mn²) – 5(6 – mn²)

= 6m²n – m³n³ – 30 + 5mn²

v) (4x2 + 7y3) (3x – 2y)

we can write 4×x×2 = 8x ; 7y3 = 21y

8x(3x – 2y) + 21y(3x – 2y)

24x² – 18xy + 63xy – 42y²

= 24x² + 45xy – 42y²
