72x2-10x-4=0x2-10x72-472=0x2-2x572+5722-5722-472=0x-5722-25+2885184=0x-5722=3135184x-572=±3135184x=572±3135184So,72x2-10x-4=x-572+3135184x-572-3135184 ANS

Factorize72x² – 10x - 4

72 x^{2} - 10 x - 4 = 0 x^{2} - \frac{10 x}{72} - \frac{4}{72} = 0 x^{2} - 2 (x) (\frac{5}{72}) + {(\frac{5}{72})}^{2} - {(\frac{5}{72})}^{2} - (\frac{4}{72}) = 0 {(x - \frac{5}{72})}^{2} - \frac{25 + 288}{5184} = 0 {(x - \frac{5}{72})}^{2} = \frac{313}{5184} x - \frac{5}{72} = \pm \sqrt{\frac{313}{5184}} x = \frac{5}{72} \pm \sqrt{\frac{313}{5184}} So, 72 x^{2} - 10 x - 4 = (x - (\frac{5}{72} + \sqrt{\frac{313}{5184}})) (x - (\frac{5}{72} - \sqrt{\frac{313}{5184}})) ANS . . .
