Question

9x^2-12x+4=0 by using completing square method

Answer 1

${9x}^{2} - 12x + 4 \\ \\ = > {(3x)}^{2} + 2(3x)( - 2) + {( - 2)}^{2} \\ = > (3x - 2)(3x - 2)$

Answer 2

$\leadsto \bf {9x}^{2} - 12x + 4 = 0 \\ \leadsto\bf {(3x)}^{2} - 2(3x)(2) + {(2)}^{2} = 0 \\ \leadsto \bf \red{(3x - 2)} \orange{(3x - 2)} = 0 \\ \\ \\ \\ \huge \boxed{ \sf \: \: \: \: x = \frac{2}{3} \: \: \: \: }$
