Hey friend,
Your answer is here..
1) 2y²-7y+2 = 0
a = 2
b = -7
c = 2
D = b²-4ac
= (-7)²-4×2×2
= 49-16
= 33
D = 33 > 0
D > 0
Therefore, roots are real and unequal.
2) m²+2m+9 = 0
a = 1
b = 2
c = 9
D = b²-4ac
= (2)²-4×1×9
= 4-36
= -32
D = -32 < 0
D < 0
Therefore, roots are unreal.
Hope it helps..
Please mark as brainliest answer if you are satisfied..
Thank you.
