Here is a sample math question typical of NECO examinations:

Question:
Solve the quadratic equation 2x2−7x+3=02x^2 - 7x + 3 = 0 using the factorization method.

  1. Identify the coefficients.

    For the quadratic equation ax2+bx+c=0ax^2 + bx + c = 0, we have a=2a=2, b=−7b=-7, and c=3c=3.

  2. Find two numbers that multiply to acac and add up to bb.

    We need two numbers that multiply to ac=(2)(3)=6ac = (2)(3) = 6 and add up to b=−7b = -7.
    The two numbers are −1-1 and −6-6, because (−1)×(−6)=6(-1) \times (-6) = 6 and (−1)+(−6)=−7(-1) + (-6) = -7.

  3. Rewrite the middle term using these two numbers.

    Replace −7x-7x with −x−6x-x - 6x:

    2x2−x−6x+3=02x^2 - x - 6x + 3 = 0
  4. Factor by grouping.

    Group the terms and factor out the common factors:

    (2x2−x)+(−6x+3)=0(2x^2 - x) + (-6x + 3) = 0 x(2x−1)−3(2x−1)=0x(2x - 1) - 3(2x - 1) = 0
  5. Factor out the common binomial.

    The common binomial factor is (2x−1)(2x - 1):

    (2x−1)(x−3)=0(2x - 1)(x - 3) = 0
  6. Set each factor to zero and solve for xx.

    For the product of two factors to be zero, at least one of the factors must be zero.

    2x−1=0orx−3=02x - 1 = 0 \quad \text{or} \quad x - 3 = 0 2x=1orx=32x = 1 \quad \text{or} \quad x = 3 x=12orx=3x = \frac{1}{2} \quad \text{or} \quad x = 3
