Question

x ^ 2 - 3sqrt(3) * x - 120 = 0​

Answer 1

Answer:

Add 3/2 to both sides to obtain:

x = 3/2 + √ 489/4

Since a square root has two values, one positive and the other negative

x2 - 3x - 120 = 0

has two solutions:

x = 3/2 + √ 489/4

or

x = 3/2 - √ 489/4

Answer 2

Step-by-step explanation:

3√3x−30=0

x 2+5√3−2√3−30=0

x(x+5√3)−2√3(x+5√3)=0

(x−2√3)(x+5√3)=0

either (x−2√3)=0 or (x+5√3)=0

x=−5√3 or 2√3
