Three normals with slopes `m_1, m_2 and m_3` are down from a point P not on the axis of the axis of the parabola `y^2 = 4x`. If `m_1 m_2` = `alpha`, results in the locus of P being a part of parabola, Find the value of `alpha`

Three normals with slopes m_1, m_2 and m_3 are drawn from a point P not on the axis of the axis of the parabola y^2 = 4x . If m_1 m_2 = alpha , results in the locus of P being a part of parabola, Find the value of alpha

Normals are drawn from a point P with slopes m_1,m_2 and m_3 are drawn from the point p not from the parabola y^2=4x . For m_1m_2=alpha , if the locus of the point P is a part of the parabola itself, then the value of alpha is (a) 1 (b)-2 (c) 2 (d) -1

Normals are drawn from a point P with slopes m_1,m_2 and m_3 are drawn from the point p not from the parabola y^2=4x . For m_1m_2=alpha , if the locus of the point P is a part of the parabola itself, then the value of alpha is (a) 1 (b)-2 (c) 2 (d) -1

Normals are drawn from a point P with slopes m_(1),m_(2) and m_(3) are drawn from the point p not from the parabola y^(2)=4x. For m_(1)m_(2)=alpha, if the locus of the point P is a part of the parabola itself,then the value of alpha is (a) 1(b)-2 (c) 2 (d) -1
