Answer» alpha and beta are zeroes that means they are solutions of the equation. To get that we have to compare equation with zero.2x^2+7x-4=02x^2+8x-x-4=02x(x+4)-1(x+4)=0so x=-4,1/2 now we have to find equation whose zeroes are 1/alpha and 1/betaso values are = -1/4,2so equation is (x+1/4)(x-2)=x^2-2x+x/4-1/2so equation is x^2-7/4x-1/2 |
