Which Of The Following Equadratic Equation Has No Real Roots?

Which of the following equadratic equation has no real roots?

 

Answer:

b2 −4ac > 0 , is your answer.

Step-by-step explanation:

b2 −4ac > 0 There are two real roots. If the discriminant of a quadratic function is less than zero, that function has no real roots, and the parabola it represents does not intersect the x-axis.

hope its helpful....

Write the standard equation or the circle: Center at C(3,4), tangent to the line y=1/3x - 1/3 and the solution please :(   Answer: (x - 3)² + (y - 4)² = 10 Step-by-step explanation: Center-Radius Standard Equation: (x - h)² + (y - k)² = r² Center (h,k): (3,4) Radius (r): Unknown Equation of line tangent to the circle: y=(1/3)x - 1/3 Point of Tangency: Unknown The radius of the circle is perpendicular to the line tangent to the same circle .   The product of theirs slopes is -1. Step 1: Find the equation passing through the center (3, 4) perpendicular to tangent line: Given tangent line: y = (1/3)x - 1/3 Slope (m₁ ) of the tangent line = 1/3 Slope (m₂) of the equation of line passing through the center: (m₂)  (1/3) = -1 m₂ = (3/1)(-1) m₂ = -3  ⇒  slope of the other line The equation of the other line with slope = -3 passing through center (3,4): y-y₁ = m(x-1) y - 4 = -3(x - 3) y = -3x + 9 + 4 y = -3x + 13 2) Find the point of tangency of the circle and the tangent line by solvi...
