Answer 1

Mark me as BRAINLIST Please I found the answer

Answer 2

Step-by-step explanation:

$On comparing 9x^2 - 12 x + 4 = 0 with ax^2 + bx + c = 0, we get :a = 9   , b = - 12 , c = 4Therefore, discriminant = b^2 -4ab  =( - 12 )^2 - 4( 9 × 4 )144 - 14  0Discriminant=0   Applyingquadratic formula,x = \dfrac{-b \pm\sqrt{discriminant}}{2a}2a−b±discriminantx = \dfrac{- ( - 12 ) \pm \sqrt{0}}{2( 9 ) }2(9)−(−12)±0x = \dfrac{ + 12 }{2( 9 )}2(9)+12x = \dfrac{2}{3}32$
