Evaluate the expression for the given value of the variable. 5×(h+3) for h=7

It is given that the quadratic equation hx²-3x+k=0, where h and k are constants, has roots [tex] \beta \: and \: 2 \beta [/tex]express h in terms of k

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
