Solve the matrix equation A=⎣⎡102−103⎦⎤ using concept of inverse.
Δ as the product of two determinants show that Δ=0 Hence show that if ax2+2hxy+by2+2gx+2fy+c=(lx+my+n)
(l′x+m′y+n) then ∣∣ahfhbfgfc∣∣=0
if a,b,c are in G.P. With common ratio r1 and αβ,γ are in G.P. with common ratio r2 and equations ax+αy+z=0
bx+βy+z=0,cx+γy+z=0 have only zero solution then which of the following is not true ?
