(b²-3) ²

To simplify the expression (b²-3) ², you will use the exponent rules.

Step 1:

Start by expanding the squared term by multiplying it by itself: (b² - 3) ² = (b² - 3)(b² - 3)

Step 2:

Multiply the terms using the distributive property: (b² - 3)(b² - 3) = b²(b²) - 3(b²) - 3(b²) + 9

Step 3:

Simplify each term: = b⁴ - 6b² + 9

So, the expression (b²-3) ² simplifies to b⁴ - 6b² + 9.
