Solve the quadratic equation [tex]\frac{x+8}{x}=\frac{x+2}{2}[/tex] Solution: x must not be zero for the equation to be defined. We cross multiply and get [tex]2(x+8)=x(x+2)[/tex], or [tex]2x+16=x^2+2x[/tex], which is equivalent to [tex]x^2=16[/tex].

L'équation quadratique peut être résolue en utilisant la formule quadratique, qui est: x = \frac { {-b \pm \sqrt { {b^2 - 4ac}}}} { {2a}} x = 2a−b± b2−4ac. La formule quadratique fournit les solutions de l'équation quadratique, qui peuvent être réelles ou complexes, en fonction du discriminant (b^2–4ac) (b2–4ac).

How do you factor a quadratic when a is not 1? To factor a quadratic (that is, to factor a trinomial of the form ax 2 + bx + c) where the leading coefficient a is not equal to 1, follow these steps: Multiply the leading coefficient a and the constant term c to get the product ac. Find factors of ac that add up to the coefficient of the constant ...
