Question

Multiply the binomial
(2y-3) and (4x-3)
(4x-5) and (4x+5)​

Answer 1

Step-by-step explanation:

(i) (2y-3) and (4x-3)

= (2y - 3)( 4x - 3)

= 2y(4x-3) -3(4x-3)

= 8xy - 6y - 12x + 9 (Ans)

(ii) (4x-5) and (4x+5)​

= (4x-5)(4x+5)​

=4x(4x+5)​ -5(4x+5)

= 16$x^{2}$ + 20x - 20x - 25

= 16$x^{2}$ - 25 (Ans)
