Question

Find the real roots : x2 +5√5x - 70=0​

Answer 1

Answer:

x2+5√5x=0+70

x2+5√5x=70

Answer 2

Step-by-step explanation:

${x}^{2} + 5 \sqrt{5} x - 70 = 0 \\ {x}^{2} + 7 \sqrt{5} x - 2 \sqrt{5} x - 70 = 0 \\ x(x + 7 \sqrt{5} ) - 2 \sqrt{5} (x + 7 \sqrt{5} ) = 0 \\ (x + 7 \sqrt{5} )(x - 2 \sqrt{5} ) = 0 \\ x + 7 \sqrt{5} = 0 \: \: \: \: \: x - 2 \sqrt{5} = 0 \\ x = - 7 \sqrt{5} \: \: \: \: \: x = 2 \sqrt{5}$
