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
