Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
bottom left
Step-by-step explanation:
when divideing/mult by neg number, sign flips.
The value of x in the equation
is x=(7+3
)/2,
(7-3
)/2.
Given equation
.
We have to find the solution of the equation.
Equation is solved to find the value of variables. The number of values of the variable depends on the highest power of variables.
let (x-5)=u-------------------1
equation becomes 
solution of a quadratic formula
x=-b±
/2a
on comparing with general form a=1,b=3, c=9
u=-3±
=-3±
=-3±
=-3±
+3
,
=-3-3
put the values of
in equation 1
x-5=
x-5=-3+
x=-3+3
x=7+3
put the values of
in equation2
x-5=
x-5=-3-3
x=7-3
Hence the values of x are 7+3
, 7-3
.
