Question

Find roots of x^2 -35 x + 10 = 0.​

Answer 1

Answer:

${x}^{2} - 35x + 10 = 0 \\ \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{ - ( - 35)± \sqrt{ {( - 35)}^{2} - 4(1)(10)} }{2 \times 1} \\ x = \frac{35± \sqrt{1225 - 40} }{2} \\ x = \frac{35± \sqrt{1185} }{2} \\ \\ x = \frac{35 + \sqrt{1185} }{2} \: \: \: or \: \: \: x = \frac{35 - \sqrt{1185} }{2}$
