Explanation Formula used: Quadratic formula: The root of the quadratic equation a x 2 + b x + c = 0 is given by; x = − b ± b 2 − 4 a c 2 a Calculation: Solve the given inequality as: 6 x 2 − x − 2 < 0 Use the quadratic formula to find the boundary points as: x = − ( − 1 ) ± ( − 1 ) 2 − 4 ( 6 ) ( − 2 ) 2 ( 6 ) = 1 ± 1 + 48 12 = 1 ± 49 12 = 1 ± 7 12 Now, use calculator to find the nearest possible boundary of x as: x = 1 + 7 12 = 2 3 And, x = 1 − 7 12 = − 1 2 Divide the number line with the help of this boundary points. This gives;

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
