Question

find the follow squares by using the identities.
(6x² - 5y)²​

Answer 1

Answer:

(6x2−5y)2

Using (a−b)2=a2−2ab+b2 we get,

(6x2)2−2(6x2)(5y)+(5y)2

=36x4−60x2y+25y2y2

Answer 2

Answer:

36x^4+60xy-25y^2

Step-by-step explanation:

using the foemula (a-b)^2=a^2+2ab-b^2

(6x^2)^2-2(6x)(5y)-(5y)^2

=36x^4-60xy-25y^2
