Answer:
x = ±√17
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other.
Also note that the x has a power of 2. To isolate the x, simply root both sides of the equation.
x² = 17 ; √x² = √17 ; x = ±√17
~
So try to get the x term to one side by itself
add 21 to both siede
3x+28=5x
subtract 3 x from both sides
28=2x
divide 2
14=x
the decimals are commas and the double decimal is a real decimal
