Question

Factorise 27xsquare - 75y square

Answer 1

Step-by-step explanation:

hi iiiiiiii hope it's right

Answer 2

Solution:-

=> 27x² - 75y²

=> 3 • (9x² - 25y²)

A² - B² can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B)

= A² - AB + BA - B²

= A² - AB + AB - B²

= A² - B²

now,

=> 3 • ( 9x² - 25y²)

=> 3 • (3x + 5y) • (3x - 5y)

I hope it helps you...
