An MCQ often asks: "Is (x - 2) a factor of x3 - 3x2 + 4x - 4?"
Don't divide! Just use the Remainder Theorem.
Substitute x = 2 into the polynomial.
If the result is 0, then it is a factor. If not, it isn't.
Mar 27, 2026 07:20 PM IST
The "Gold Standard" Division Steps of Polynomial
- Always write the terms in descending order of their powers.
- If a power is missing (such as x3-1), then candidates should write it as x3+ 0x2+ 0x-1. This will prevent the alignment errors.
- When the candidates subtract, then change the sign of every term in the bottom row.

Quadratic Equations: The "Formula Method" Pro-Tips
The Board usually asks the students to solve using the formula."
Formula:
- The sign trap: If the value of b is already negative, then -b will be -(-b)= +b. This is the primary mistake that most of the students make.
- The 2a denominator: Do not forget that the division line goes under the entire numerator, not just the square root part.
- Standard Form first: Before starting to solve, the candidates should rearrange the equation as ax2+bx+c=0 before picking a, b, c.

- Do not mess with the formula. If you are unable to complete the answer correctly, then you will get step marks for correctly writing the formula.
- Do not get stuck on solving one problem; it will take more than 10 minutes. Instead, leave the sum and move to the next one.
- Do not forget to add units (cm, m, etc.). Otherwise, you will lose half a mark per question.
