Answer:

1. alternate form ;P¹≈-2.68614,P²≈0.186141

Step-by-step explanation:

2p²+5p-1=0

solve the quadratic equetion .ax²+bxc=0

• using x=-b±√b²-4x2x(-1)

---------------------------

2a

p=-5±√5²-4x2x2x(-1)

-------------------------------

2(2)

evaluate the power

p=-5±√25-4x2x(-1)

---------—–—————

2(2)

next is add the no.

p= -5±√25-4x2x(-1)

-----------------------------

2(2)

p=-5±√33

----------------

4

p= -5+√33

---------------

4

p=-5-√33

---------------

4

the equetion has 2 solution

p¹=-5-√33,p²=-5+√33

--------------, ----------------

4 4

alternate form:(P¹≈2.68614,P²≈0.186141)

thats the final answer
