<h2>Polynomial</h2>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Given
x² + 4x -12 is a polynomial.
<h3>How to factorize the polynomial?</h3>
x² + 4x - 12
Step 1. x² + 6x - 2x -12
Step 2. (x² + 6x) - (2x + 12)
Step 3. x(x + 6) - 2 (x + 6)
Step 4. (x + 6)(x - 2)
Thus, in fourth step in place of (x + 2), (x - 2) is to be put.
Thus, The fourth step is incorrect.
