You expansion of y-8 whole square is wrong. It should be y^2-16y+64. U made a mistake in middle term and written it as -32y. Please rectify ur mistake and redo it without any mistakes.
You are genius and so sweet my friend. please check the title I already say about to find the mistake...Thanks
This calculation is wrong. A simple check shows it.
Is the actual answer (root of -1024) - 5? or -32i - 5?
If x=3 is the solution, how do you solve sqrt(-2)?
(y-8)^2=y^2+8^2-2×y×8 not (y-8)^2=y^2+8^2-4×y×8 (6:11 minut)
Wrong solution. if x=3, then the first part is complex number which is not equal with 4
let u=V(x+5) , u+i*u=4 , u(1+i)=4 , u=4/(1+i) , u=4/(1+i)*(1-i)/(1-i) , u=2-2i , (V(x+5))^2=(2-2i)^2 , x+5=-8i , x=-8i-5 , test , V(-8i-5+5)+V(i(-8i-5+5))=V(-8i)+V(8i) , V(-8i)+V(8i)=2-2i+2+2i , --> 4 , OK , solu , x= -8i-5 ,
