Explanation Given: The given equation is, 4 2 x 2 + 3 x − 9 + 2 2 x 2 − x − 3 = 3 x 2 + 4 x + 3 Approach: For all real numbers a , b and c . 1. If a = b , then a + c = b + c . 2. If a = b , then a c = b c . Zero factor property. If a and b are real numbers, with a b = 0 , then either, a = 0 or b = 0 , or both. The solutions of the quadratic equation a x 2 + b x + c = 0 , where a ≠ 0 , are given by, x = − b ± b 2 − 4 a c 2 a Calculation: Consider the equation. 4 2 x 2 + 3 x − 9 + 2 2 x 2 − x − 3 = 3 x 2 + 4 x + 3 Simplify the above expression. 4 2 x 2 + 6 x − 3 x − 9 + 2 2 x 2 − 3 x + 2 x − 3 = 3 x 2 + x + 3 x + 3 4 2 x ( x + 3 ) − 3 ( x + 3 ) + 2 x ( 2 x − 3 ) + 1 ( 2 x − 3 ) = 3 x ( x + 1 )

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.
