Question 1

1.1 Solve for 𝑥 :

1.1.1 (2𝑥 – 3)(𝑥 + 7)= 0 (2)

1.1.2 7𝑥² + 3𝑥 – 2 = 0 (leave your answer correct in TWO decimal places ) (3)

1.1.3 (2)

1.1.4 𝑥² > 3(𝑥 + 6) (2)

1.2 Solve for 𝑥 and 𝑦 simultaneously :

2𝑦 + 𝑥 = 1

𝑥² + 𝑦² + 3 𝑥𝑦 + 𝑦 = 0 (6)

1.3 if 𝑓(𝑥) = 0 has roots for which values of 𝑘 will the roots be equal ? (3)
