Answer: (2y-3)² Step-by-step explanation: 4y²-12y+9 We will use identity a²-2ab+b²=(a-b)² =(2y)²-2×2y×3+(3)² =(2y-3)² Reply
Q.4y² – 12y + 9
= 4y² – 6y – 6y + 9
= 2y (2y – 3) – 3 (2y – 3)
= (2y – 3) (2y – 3)
= (2y – 3)²
Answer:
(2y-3)²
Step-by-step explanation:
4y²-12y+9
We will use identity a²-2ab+b²=(a-b)²
=(2y)²-2×2y×3+(3)²
=(2y-3)²
