Question

) Simplify:
i)
(x - 2) (x - 3)
(4x - 9y) (4x + gy)
ii)​

Answer 1

Answer:

$(i) \\ (x - 2)(x - 3) \\ = {x}^{2} - 2x - 3x + 6 \\ = {x}^{2} - 5x + 6 \\ (ii)(4x - 9y)(4x + 9y) \\ = 16 {x}^{2} - 81 {y}^{2}$

Answer 2

Step-by-step explanation:

i) (x- 2) (x- 3)

solve:

= x^2 - 3x - 2x +6

= x^2 - 5x + 6

ii) ( 4x- 9y ) (4x + gy )

Solve:

= 16x^2 + 4xgy - 36xy - 9gy^2

= 16x^2 - 9gy^2 + 4xgy - 36xy Answer
