Solving quadratics graphically bbc bitesize
WebQuadratic equations can have two different solutions or roots. You may need a quick look at 'factorising' again to remind yourself how to factorise expressions such as: x2 − x − 6. which factorises into (x − 3) (x + 2), a 2 − 3a. which factorises into a (a − 3) and. b 2 − 2b + 1. which will factorise into (b − 1) 2.
