..Find the factors of and use them to solve teh quadratic equation:
Mr F says: You really must (re-?)learn to factorise.
Therefore either 4x - 3 = 0 or x + 4 = 0. Therefore x = .......
Solve the quadratic equation
Mr F says: Use the quadratic formula (there are probably more websites explaining the quadratic formula and how to use it than you've had hot breakfasts). Or factorise:
Therefore either 2x + 1 = 0 or x - 1.3 = 0. Therefore x = ....
Ive been reading higher engineering mathamatics by John Bird but i still dont get it or know where to start. Help is much apreciated.
Mr F says: Uh huh. The hard fact is that a textbook with that title is gonna be pitching way over your head, bud. You need a maths textbook pitched at high school level. Or google solving quadratic equations and find a website that floats your boat.
If you can break it into steps so i dont egt lost again that would help.
