Factor Completely

k²+7x+10

• k = 2, k = 5

• k = -2, k = -5

• (k-2)(k-5)

• (k+2)(k+5)

Factor Completely

n² + 16n + 63

• (n-7)(n-9)

• (n+7)(n+9)

• n = 7, n = 9

• n = -7, n = -9

Solve by factoring:

2x²+ 7x + 6 = 0

• x= 3/2 and x = 2

• x = -3/2 and x = -2

• (2x - 3)(x - 2)

• (2x + 3)(x + 2)
