Answer 2

hey your answrr of this question

${{x}^{2}\:+\:30 \:= \:1000 }$

${{x}^{2}\:+\:30 \:-\:1000\:= \:0 }$

${{x}^{2}\:+\:50x\:-\:20x \:-\:1000\:= \:0}$

${(x\:+\:50)\:-\:20(x \:+\:50)\:= \:0 }$

${(x\:-\:20)(x \:+\:50)\:= \:0 }$

x - 20 = 0. or x + 50 = 0

x = 20. or x = - 50

20 , -50 are the roots of the equation
