#2.7A
solve quadratic equations by factorisation (limited to \(x^2 + bx + c = 0\))
Solve \(x^2 + x - 30 = 0\)
#2.7B
solve quadratic equations by factorisation
\(2x^2 - 3x + 1 = 0\)
\(x(3x - 2) = 5\)
#2.7C
solve quadratic equations by using the quadratic formula or completing the square
#2.7D
form and solve quadratic equations from data given in a context
#2.7E
solve simultaneous equations in two unknowns, one equation being linear and the other being quadratic
\(y = 2x - 11, x^2 + y^2 = 25\)
\(y = 11x - 2, y = 5x^2\)
