Answer:
x = (1/2) (-9 ± √73)
Step-by-step explanation:
Using completing the square method
x²+9x+2=0
x²+9x = -2 (complete the square by adding (9/2)² to both sides)
x²+9x + (9/2)² = -2 + (9/2)²
( x + (9/2) )² = -2+ (9/2)²
( x + (9/2) )² = -2+ (81/4)
( x + (9/2) )² = 73/4
x + (9/2) = ± √(73/4)
x + (9/2) = ± √(73) / 2
x = -(9/2) ± √(73) / 2 (factorize out (1/2) )
x = (1/2) (-9 ± √73)

Answer:
The fraction 58/60 is equal to 29/30 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (29/30) by any interger number, ie, multiply by 2, 3, 10, 30... 58/60 is equivalent to 29/30 because 29 x 2 = 58 and 30 x 2 = 60
