Question

evaluate (4a square + 3b) (4a square + 3b)
​

Answer 1

Answer:

= 9b² - 24ab + 16a²   or  16a² - 24ab + 9b²

Step-by-step explanation:

Pattern 1: (a + b)² = a² + 2(a)(b) + b²

Pattern 2: (a - b)² = a² - 2(a)(b) + b²

lets use pattern 2:

(a - b)² = a² - 2(a)(b) + b²

(3b - 4a)² = (3b)² - 2(3b)(4a) + (4a)²

               = 9b² - 24ab + 16a²   or  16a² - 24ab + 9b²
