How to factorise large quadratics

WebWhat we're going to do in this video is do a few more examples of factoring higher degree polynomials. So let's start with a little bit of a warmup. Let's say that we wanted to factor six x squared plus nine x times x squared minus four x plus four. Pause this video and see if you can factor this into the product of even more expressions. Web24 de oct. de 2024 · Thus u = 29 and v = 8, so the desired factorisation is ( 3 n − 29) ( n − 8) Another approach is to complete the square, but it is a bit tedious, and the numbers may get too large for rapid mental calculation. We need the leading coeffient to be a square, and the coefficient of the n term to be even. So we have to multiply this expression by 12.
