42) If \( \alpha \) and \( \beta \) are the roots of the equation \( x^{2}+x-4=0 \) form the quadratic equation whose roots are \( \alpha^{2} \) and \( \beta^{2} \).
given-: a+b=-1............ eqn ¹ ab=-4. ............. eqn ² on squaring eqn ¹ a²+b²+2ab=1 a²+b²=9 on squaring eqn ² a²b²=16 hence the eqn is x²+9x+16=0 ♥
