Question

factorise 3x²- 14x +3​

Answer 1

Answer:

$3( {x}^{2} - \frac{14}{3} x + 1) =$

$3( {x}^{2} - 2 \times x \times \frac{7}{3} + \frac{49}{9} - \frac{49}{9} + 1) =$

$3((x - \frac{7}{3} ) {}^{2} - \frac{40}{9} ) =$

$3((x - \frac{7}{3} ) {}^{2} - ( \frac{2 \sqrt{10} }{3} ) {}^{2} ) =$

$3((x - \frac{7}{3} + \frac{2 \sqrt{10} }{3} )(x - \frac{7}{3} - \frac{2 \sqrt{10} }{3} )$
