Question

5p²- 10p+8=0
????find p......​

Answer 1

Answer:

The value of p is ( 10 + √-60 / 10 ) or ( 10 - √-60 / 10 ).

Step-by-step explanation:

5p² - 10p + 8 = 0

Comparing with ax² + bx + c = 0,

• a = 5
• b = - 10
• c = 8

b² - 4ac = (-10)² - 4 * 5 * 8

=> b² - 4ac = 100 - 20 * 8

=> b² - 4ac = 100 - 160

=> b² - 4ac = - 60

Now,

p = [ - b ± √(b² - 4ac) ] / 2a

=> p = [ - (-10) ± √-60 ] / 2 * 5

=> p = 10 ± √-60 / 10

So,

The value of p is ( 10 + √-60 / 10 ) or ( 10 - √-60 / 10 ).
