Plugging into the original equation gives: C = Y1 - AX1^2 - BX1 This all looks horrible, but we have the values for Y1, Y2, Y3, X1, X2, and X3 so we just plug them in. The example does that to find A, B, and C. It then graphs the function so you can see it passes th...

The two roots of the quadratic equation (3.57)ax2+bx+c=0 are given by one of the most useful formulas in elementary algebra. We don’t generally spend much time deriving formulas, but in this one instance, the derivation is very instructive. Consider the following very simple polynomial whi...

The given quadratic equation is 2x2+ 9x + 7 = 0. Hence the required equation having reciprocal roots is 7x2+ 9x + 2 = 0. Method 2:From the given equation, α + β = -9/2 and αβ = 2/7. The new equation should have its roots to be 1/α and 1/β. ...
Quadratic equation is a second order polynomial with 3 coefficients -a,b,c. The quadratic equation is given by: ax2+bx+c= 0 The solution to the quadratic equation is given by 2 numbers x1and x2. We can change the quadratic equation to the form of: ...
Such an equation has two roots (not necessarily distinct), as given by the quadratic formula x = − b ± b 2 − 4 a c 2 a The discriminant b2 − 4ac gives information concerning the nature of the roots (see discriminant). If, instead of equating the above to zero, the curve...
