Solve the following quadratic equations by factorization.

(1) x² – 15x + 54 = 0

Solution:

(2) x² + x – 20 = 0

Solution:

(3) 2y² + 27y + 13 = 0

Solution:

(4) 5m² = 22m + 15

Solution:

(5) 2x² – 2x + ½ = 0

Solution:

(2x – 1) (2x – 1)

2x – 1 = 0

x = ½, ½

Hence x = ½, ½ are the roots of the equation

(6) 6x -2/x = 1

Solution:
