Question

What is wrong in the sum I did? And if nothing's wrong, then how will the sum progress?

-13x²+8x+12

=-13x²+6x+2x+12

But it did not come.

How will the sum progress and what did I do wrong?

Answer 1

Hi!

Here is the answer to your question.

All quadratic polynomials cannot be factorized by splitting their middle term.

The given polynomial is –13x² + 8x + 12.

This polynomial cannot be factorized by splitting the middle term. The reason for this will be taught in Class X.
