How to factorise expressions with 4 terms
Web4 Write one factor in the first bracket and the other factor in the second bracket. The order isn’t important, the signs of the factors are. (x +1)(x +5) ( x + 1) ( x + 5) We have now fully factorised the quadratic expression. We can check the answer by multiplying out the brackets! (x +1)(x +5) = x2 +6x +5 ( x + 1) ( x + 5) = x 2 + 6 x + 5 WebSometimes a quadratic polynomial, or just a quadratic itself, or quadratic expression, but all it means is a second degree polynomial. So something that's going to have a variable raised to the second power. In this case, in all of the examples we'll do, it'll be x. So let's say I have the quadratic expression, x squared plus 10x, plus 9.
