Please help!!! I need someone to use some brain power

Answer 1

Answer:

• r = 4, s = 3, t = 5

Step-by-step explanation:

Solving quadratic equation:

• 5x² - 8x + 5 = 0
• x = (-b ± √b²-4ac)/2a
• x = (8 ± √8²-4*5*5)/2*5
• x = (8 ± √64-100)/10
• x = (8 ±√-36)/10
• x = (8 ± 6i)/10
• x = (4 ± 3i)/5

x = (r ± si)/t

r = 4, s = 3, t = 5
