Solve 3

Solve quadratic equation:

(6n+1) (4n-1) = 3n2

Correct answer:

n1 =  0.271
n2 =  -0.1757

Step-by-step explanation:

(6n+1)(4n1)=3n2  21n22n1=0  a=21;b=2;c=1 D=b24ac=22421(1)=88 D>0  n1,2=b±D2a=2±8842=2±22242 n1,2=0.04761905±0.22335313142 n1=0.270972179039 n2=0.175734083801   Factored form of the equation:  21(n0.270972179039)(n+0.175734083801)=0  n1=0.271

Our quadratic equation calculator calculates it.

n2=(0.1757)=0.1757
