the equation 0 = x2 – 8x – 13?

Answer 1

x= 32 ± √29

Explanation:

x² - 8x - 13 = 0

ax² + bx + c = 0

Comparing equations we get,

a=1

b=(-8)

c=(-13)

Using quadratic formula,

________

x= b² ± √ b²-4ac

—————————

2a

Substituting the values

__________

x= 64 ± √( 64 + 52)

______________

2

= 32 ± √29
