Answer:
Step-by-step explanation:
Hi there!
9a² - b² + 4b - 4
= 9a² - (b² - 4b + 4). [Taking '-' common from the three terms]
= 9a² - [(b)² - (2 x b x 2) + (2)²]
= 9a² - (b - 2)² [As, a² - 2ab + b² = (a - b)²]
= (3a)² - (b - 2)²
= (3a + b - 2)[3a - (b - 2)] [As, (a + b)(a - b) = a² - b²]
= (3a + b - 2)(3a - b + 2)

What is an example of algebra?
For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

What are the 4 steps to solving an equation?
Different ways to solve equations. We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal.
