Let's Evaluate
A Complete the table below.
EQUATION
X²- 14x + 49 = 0
2x² – 3x – 10 = 0
4x² - 2x - 6=0
2x²-X-3=0
4x² - X + 3 = 0
I need
B²-4ac and Nature of the Roots
Please Help me I want to Answer this

Step-by-step explanation:
x² - 14x + 49 = 0
D = b² - 4ac
= (-14)² - 4(1)(49)
= 196 - 196
D = 0
One real,unequal root,rational
2x² - 3x - 10 = 0
D = (-3)² - 4(2)(-10)
= 9 - (-80)
D = 89
Two real, unequal roots, irrational
4x² - 2x - 6 = 0
D = (-2)² - 4(4)(-6)
= 4 - (-96)
D = 100
Two real,unequal roots,rational
2x² - x - 3 = 0
D = (1)² - 4(2)(-3)
= 1 - (-24)
D = 25
Two real,unequal roots,rational
4x² - x + 3 = 0
D = (1)² - 4(4)(3)
= 1 - 48
D = -47
No real root
