Question

Determine the type and number of solutions:

1.) x^2 + 5x - 6 = 0

2.) n^2 + 16 = -8n

Answer 1

Explanation:

1. Question: x² + 5x -6 =0

Answer: x²+2x+3x-6

x(x+2)-3(x+2)

( x-3) (x+2)

x-3=0. x+2=0

x=3. x=-2

2. Question: n²+16=-8n

Answer: n²+8n+16=0

n²+4n+4n+16

n(n+4)+4(n+4)

(n+4) (n+4)

n+4=0. n+4=0

n=-4. n=-4

hope this helps you

have a great day :)
