Question

Solve the equation x^2-3x-2=0 giving your answer correct to 2 decimal places. I am getting the answer but it’s not in decimals please helppp!!!

Answer 1

Answer:

Step-by-step explanation:

x²-3x-2=0

delta = b² - 4ac        a=1      b = -3        c = -2

delta = (-3)² - 4(1)(-2) =17

X1 = (3-√17)/2  ≃ - 0.56

x2 =(3+√17)/2  ≃3.56
