Y 2 2y 2. Decompose 54 into two factors such that the product of two factors is equal to 54 and the addition of two factors is equal to the coefficient of x that is 15. A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign.
Then substitute 1 2 and 2 for a b and c respectively in the quadratic formula and simplify.
A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign. Quadratic equations are also needed when studying lenses and curved mirrors. The Quadratic Formula is an algebraic formula used to solve quadratic equations. In algebra a quadratic equation is any equation that can be rearranged in standard form as a x 2 b x c 0 displaystyle ax2bxc0 where x represents an unknown and a b and c represent known numbers where a 0.
