Question
Solve the equation
Solve for x
Solve for w
w=0,x=−4∣w∣2170ww=0,x=4∣w∣2170w
Evaluate
0=2x2×8w−2170
Multiply the terms
0=16x2w−2170
Rewrite the expression
0=16wx2−2170
Swap the sides of the equation
16wx2−2170=0
Move the constant to the right-hand side and change its sign
16wx2=0+2170
Removing 0 doesn't change the value,so remove it from the expression
16wx2=2170
Divide both sides
16w16wx2=16w2170
Divide the numbers
x2=16w2170
Cancel out the common factor 2
x2=8w1085
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±8w1085
