Compare 16 x2 + 8x +1 = 0 with the standard form ax2 + bx + c = 0 and give the values of a, b and c.
Solve using the quadratic formula.
x2 – 6x = 16
x2 = 4x – 4
2y2 – 3y – 2 = 0
Compare (x + 5)2 = 0 with the standard form ax2 + bx + c = 0 and give the values of a, b and c.
Solve using the quadratic formula. Round your answer to two decimal places.
3x2 + 12x + 18 = 0
–x2 + 7x – 13 = 0
x2 = 7x – 9
4x2 + 12x – 7 = 0
x2 – 4x + 9 = 0
