In the equation

y = x² + 5x + 7, match each coefficient with its correct letter

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

Identify the values of a, b and c

(Hint : remember to put in Standard Form first)

11r² + 6r = 6

• a=11, b=-6, c=-6

• a=11, b=6, c=6

• a=11, b=6, c=-6

• a=1, b=6, c=-6

Solve using the Quadratic Formula

2x² + 2x - 12 = 0
