Your equation should have been
25y^2 - 60y + 324 = 0
by the formula:
y = (60 ±√-28800)/50
= (60 ± 120√-2)/50
= (6 ± 12i√2)/5
which is a complex number
can you please help me with this problem:
30y2^ + 60y + 300 = 5y2^ + 120y -24
25y - 60y + 324 = 0
used the quadratic equation (used the square root)
x = -60 (60)2^ - 4(25)(324) / 50
x = -60 (3600 + 32,400)/50
x = -60 +or minus(-28,800) / 50
x = -60 + 169.706 / 50 = 109.706/50
x = 2.19
x = -60 - 169.706 / 50 = -229.706 / 50
x = -4.59
I tried to show of my work the best as possible - thank you
