If line 3x+y 8 meets parabola
WebA line which intersects the ellipse at a point is called a tangent to the ellipse. The different forms of the tangent equation are given below: Slope form of a tangent to an ellipse; If the line y = mx + c touches the ellipse x 2 / a 2 + y 2 / b 2 = 1, then c 2 = a 2 m 2 + b 2. The straight line y = mx ∓ √[a 2 m 2 + b 2] represent the ... Web23 jul. 2015 · Let the equation of the tangent be y = 3 x + c Now, solving the equation of the tangent line: y = 3 x + c & the parabola: y = x 2 − 3 x − 5 by substituting y = 3 x + c as follows 3 x + c = x 2 − 3 x − 5 (1) x 2 − 6 x − ( c + 5) = 0 For tangency we have the following condition determinant, B 2 − 4 A C = 0 ( − 6) 2 − 4 ( 1) ( − ( c + 5))

WebThe straight line x + y = k touches the parabola y = x – x2, if k = Maths-General since only one point of contact is present, D=0 gives the real root. General Maths- If the line x + y –1 = 0 touches the parabola y2= kx, then the value of k is- we can also solve for the two lines and make the D=0 for the resultant quadratic equation. WebThere is also a special case when the line is parallel to the \(y\)-axis. In this case the line will cut the parabola once. Having noted this case, we will not need to consider it further, since the intersection point is easily found. Suppose the line has the form \(y=mx+d\) and the parabola is \(y=ax^2+bx+c\). Equating, we have
