Question 67297
x^2+(x+5)^2=(x+10)+125
x^2+x^2+10x+25=x+135
2x^2+10x-x+10-135=0
2x^2+9x-125=0 using the quadratic equation x=(-b+-sqrt[b^2-4ac])/2a we get
x=(-9+-sqrt[81-4*2*-125])/2*2
x=(-9+-sqrt[81+000])/4
x=(-9+-sqrt1081)/4
x=(-9+-32.87856)/4
x=(-9+32.87856)/4
x=23.878564/4
x=5.96964 solution
x=(-9-32.87856)/4
x=-41.87856/4
x=-10.46964 solution
