option b. 1.93, -11.93 is the right answer.
here the given equation is x²-23 = 10x and we have to solve the equation for the value of x.
first we simplify the equation to bring in the shape of ax²+bx+c=0
x²-23 = 10x
(x²-23)-10x = 10x-10x
x²-10x -23 = 0
now we the formula for the value of
now x = (-5+6.93) = 1.93
and x = (-5-6.93) = -11.93
30 / 0.350 = 85.7
