The coefficient 'a' for the quadratic term is a = 3 The coefficient 'b' for the linear term is b = -2 The coefficient 'c' is 0 Step-by-step explanation : The given expression is,
To solve this problem we are using quadratic formula. The general quadratic equation is,
Formula used :
Now we a have to solve the above equation and we get the value of 'x'.
a = 3, b = -2, c = 0
The coefficient 'a' for the quadratic term is a = 3 The coefficient 'b' for the linear term is b = -2 The coefficient 'c' is 0
The modulus of complex number can be computed with this equation: |z|=sqrt(Re(z)^2+Im(z)^2) z = -2-6i Re(z)=-2, so Re(z)^2=4 Im(z)=-6, so Im(z)^2=36 |z|=sqrt(36+4)=sqrt(40)=6.3
