What are expanding and factorising?

Area model showing a rectangle split into four parts for expanding (x + 4)(x + 3), with cells labelled x squared, 4x, 3x, and 12, then simplified to x squared plus 7x plus 12.

A quadratic expression has highest power 2, such as x2+6x+8x^2 + 6x + 8x2+6x+8. Expanding means removing brackets by multiplying, and factorising means writing the quadratic back as a product of brackets.
