Question

factorise 27x²-48y²​

Answer 1

factorise

27x^2 - 48y^2

Solution

$( \sqrt{27} \times x - \sqrt{48} \times y)( \sqrt{27} \times x + \sqrt{48} \times y)$

Answer 2

Answer:

3 (3x + 4y) (3x-4y)

Step-by-step explanation:

formula --->

________

a^2-b^2=(a+b)(a-b)

= 27 x^2- 48 y^2

= 3(9x^2 - 16y^2)

=3 { (3x) ^2 - (4y) ^2 }

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