Question

( 9 x^{2}-12 x+20=0 )
(2) If take any term cammon as it will make theieg". complax.
( because quad frac{d x}{d x} cdot x=-frac{-b pm sqrt{D}}{2 a} )
( =frac{12 pm sqrt{(12)^{2}-4 times 9 times 20}}{12 pm sqrt{144-720}} )
( =frac{12 pm 18}{18} )
( theta )
( =frac{12 pm sqrt{-576}}{18} )
since ( D<0 Rightarrow ) no. real value of ( x ) exist

# Ми - 12 и 10 hts s2 - Ии) +20 - Ин) + (90 12
