The roots of the quadratic equation 2x^2 - x - 6 = 0 are

Use formula to solve the quadratic equation : x^2 + x - (a + 1) (a + 2) = 0.

Let A be a square matrix such that A^2-A+I=O , then write A^(-1) in terms of Adot

The quadratic equation x^(2) - (m -3)x + m =0 has

Let x_(1),x_(2) are the roots of the quadratic equation x^(2) + ax + b=0 , where a,b, are complex numbers and y_(1), y_(2) are the roots of the quadratic equation y^(2) + |a|yy+ |b| = 0 . If |x_(1)| = |x_(2)|=1 , then prove that |y_(1)| = |y_(2)| =1

Let A be an mxxn matrix. If there exists a matrix L of type nxxm such that LA=I_(n) , then L is called left inverse of A. Which of the following matrices is NOT left inverse of matrix [(1,-1),(1,1),(2,3)]?

Statement -1 : A root of the equation (2^(10)-3)x^(2)-2^(11)x +2^(10)+3 =0 " is " 1 and Statement-2 : The sum of the coefficients of a quadratic equation is zero, then 1 is a root of the equation.
