6x^2 + 42x=0
-------
Divide by 6
x^2 + 7 = 0
x^2 = -7
x = +i*sqrt(7)
x = -i*sqrt(7)
i = sqrt(-1)

6x%5E2%2B42x=0 Start with the given equation


6x%28x%2B7%29=0 Factor out the GCF 6x



Now set each factor equal to zero:


6x=0 or x%2B7=0



x=0 or x=-7 Now solve for x in each case


So the answers are


x=0 or x=-7
