Question

Can someone help me

5b^2+4=10b

Answer 1

b = 5 ± √5 / 5

Explanation:

Given :

• 5b² + 4 = 10b

Subtract 10b from both sides :

• 5b² - 10b + 4 = 10b - 10b
• 5b² - 10b + 4 = 0

Splitting the middle term :

• b = 10 ± √100 - 4(5)(4) / 10
• b = 10 ± √20 / 10
• b = 10 ± 2√5 / 10
• b = 5 ± √5 / 5
