Answer:

1.4x²-5√2+8=0

2.7x²-3x-4=0

Step-by-step explanation:

1.by formula

D = b²-4ac

a=4 , b=5√2 , c=8

(5√2)² - 4×4×8

25×2 - 128

50 - 128

-78

b² -4ac Not equal to zero and not perfect square root so it is

real,unequal and irrational

2.

a=7 , b=-3 ,c=-4

b² - 4ac = 0

(-3)² - 4 ×7×(-4) = 0

=9 + 112

=121

it is a perfect square root so it is

real unequal and rational
