To solve for x, you need to isolate/get x by itself in the equation:
Square ² both sides to get rid of the square root √
x - 2 = 0 Add 2 on both sides
x - 2 + 2 = 0 + 2
x = 2
The 77th term is 532 because the nth term is 7n-7
7x77=539
539-7=532
Step-by-step explanation:
so basically they are asking you to subtract, hope this helps, use a calculator if needed
a+b+c=0
[(a+b+c)^2=a^2+b^2+c^2+2ab+2ac+2bc]
[a^2+b^2+c^2+2ab+2ac+2bc=0]
[a^2+b^2+c^2=-(2ab+2ac+2bc)]
[a^2+b^2+c^2=-2(ab+ac+bc)] (i)
also
[a=-b-c]
[a^2=-ab-ac] (ii)
[-c=a+b]
[-bc=ab+b^2] (iii)
adding (ii) and (iii) ,we have
[a^2-bc=b^2-ac] (iv)
devide (i) by (iv)
[(a^2+b^2+c^2)/(a^2-bc)=(-2(ab+bc+ca))/(b^2-ac)]
