(x-6) (x-6) =?(a) (x2-36) (b) (x2+36) (c) (x2-6x+36) (d) (x2-12x+36

1.	(x-6) (x-6) =?(a) (x2-36) (b) (x2+36) (c) (x2-6x+36) (d) (x2-12x+36)
Answer» (d) (x²-12x+36) Explanation: Given (x-6) (x-6)=(x-6)² By expanding the given expression by using (a – b)²= a²-2ab+b²we get (x-6)² = x²-2(x) (6)+6² = x²-12x+36

(x-6) (x-6) =?(a) (x2-36) (b) (x2+36) (c) (x2-6x+36) (d) (x2-12x+36)

Answer»

(d) (x²-12x+36)

Explanation:

Given (x-6) (x-6)=(x-6)²

By expanding the given expression by using (a – b)²= a²-2ab+b²we get

(x-6)² = x²-2(x) (6)+6² = x²-12x+36
