Explanation Formula used: Quadratic formula If a x 2 + b x + c = 0 , a ≠ 0 , then x = − b ± b 2 − 4 a c 2 a . Calculation: The given equation is 2 − 2 m 2 = 3 m . Multiply by m 2 on both sides. ( 2 − 2 m 2 ) m 2 = 3 m ⋅ m 2 2 m 2 − 2 = 3 m Subtract the term 3 m on both sides. 2 m 2 − 2 − 3 m = 3 m − 3 m 2 m 2 − 3 m − 2 = 0 Solve the above quadratic equation by quadratic formula as follows. Here a = 2 , b = − 3 and c = − 2 . Substitute the above values in the formula x = − b ± b 2 − 4 a c 2 a

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.
