Algebra Ex.21. Find the value of m such that the equation for real values of x. 4. If the roots of the equation ax²+cx+c=0 be in the ratio m:n, prove that 5. If the equations x²+bx+ca=0 and x²+cx+ab=0 have a common root, show that their roots will satisfy the equation x²+ax+bc=0. Character is who you are when no one is looking.
