Answer:

y = 5x² - 80x + 324

Explanation:

the quadratic function in standard form is

y = ax² + bx + c ( a ≠ 0 )

given

y = 5(x - 8)² + 4 ← expand the factor using FOIL

= 5(x² - 16x + 64) + 4 ← distribute parenthesis by 5

= 5x² - 80x + 320 + 4 ← collect like terms

= 5x² - 80x + 324 ← in standard form
