Final answer:
To simplify the expression (5z² - 3z + 2)², we need to square each term within the parentheses.
Step-by-step explanation:
To simplify the expression (5z² - 3z + 2)², we need to square each term within the parentheses.
Using the formula for squaring a binomial, we have: (a + b)² = a² + 2ab + b².
Applying this formula to our expression, we get: (5z² - 3z + 2)² = (5z²)² + 2(5z²)(-3z) + (-3z)² + 2(5z²)(2) + 2(2)(-3z) + 2².
This simplifies to: 25z^4 - 30z^3 + 10z² - 30z² + 36z + 4.
