Answer:
(5b-6)^2
Step-by-step explanation:
by using formula
(a-b)^2 = (a)^2 - 2(a)(b) + (b)^2
by putting values in the above formula
(5b)^2 - 2(5b)(6) + (6)
(5b-6)^2 answer
Answer:
(5b - 6)(5b - 6)
Step-by-step explanation;
25b^2 - 60b + 36
=> (5b)^2 - 2 × 5b × 6 + (6)^2 [Using (a + b)^2 = a^2 + b^2 + 2ab]
=> (5b - 6)^2
=> (5b - 6)(5b - 6)
