Question

Solve x in the equation x^2-12+59=0

Answer 1

Answer: You use the quadratic formula

X= i√47, −i√47

Answer 2

Therefore the value of x = [144 ± √-92]/2

Explanation:

Formula: Let ax² + bx +c = 0 be the quadratic equation.Then,

x = [-b ± √(b²-4ac)]/2a

Here quadratic equation be x² - 12x + 59 =0

a = 1, b = -12 and c = 59

x = [-b ± √(b²-4ac)]/2a

x = [-(-12) ± √((-12)²-4*1*59)]/2

x = [144± √(144-236)]/2

x = [144 ± √-92]/2

Therefore the value of x = [144 ± √-92]/2
