Luas persegi panjang =253 M persegi, panjang =23 M Maka lebar=.... M
Answer (3)
x² + 3x + 3 = 0
I can tell by looking that there's no easy way to factor the left side, so we'll have to use the Quadratic formula.
Before doing that, let's just take a look at the discriminant:
( B² - 4AC ) = (9) - (4 x 3 x 1) = (9 - 12) = -3 . The discriminant is negative, so we know that the roots will be complex conjugates.
Again: x² + 3x + 3 = 0
x = (1/2) [ -3 plus or minus the square root of (-3) ]
x = -3/2 + (1/2) j√3 and x = - 3/2 - (1/2) j√3
The solutions to the equation x 2 + 3 x + 3 = 0 are complex numbers due to a negative discriminant. Using the quadratic formula, we find the solutions to be x = − 2 3 ± 2 i 3 . This indicates that there are no real roots, only complex conjugate solutions.
