What if my equation doesn't factorise?

For all quadratic equations, you can use the quadratic formula. Given an equation of the form ax2+bx+c, you can plug those values into this formula:

x1, x= (-b +/- sqrt(b- 4ac)) / 2a

Note: the term b- 4ac is called the determinant  and must be greater than 0 for your equation to have any solutions.

Simplify the expression: 3x + 2y -7x + c + y

Solve algebraically: 6x + y = 16, 5x - 2y = 19

If x^2 = 16, why isn't the answer just x = 4?

Solve the two simultaneous equations: 2y + x = 8 [A] and 1 + y = 2x [B]
