What are the terms in the expression x3 - 5x - 18 + 8x2?
Solution: User:
What are the terms in the expression x3 - 5x - 18 + 8x2?
Solution: **Weegy:** The answer is x=(1)/(2). [ 5-(x+2)=5x
Multiply -1 by each term inside the parentheses (x+2).
5-(x)-(2)=5x
Multiply -1 by the x inside the parentheses.
5-x-(2)=5x
Multiply -1 by the 2 inside the parentheses.
5-x-2=5x
Subtract 2 from 5 to get 3.
3-x=5x
Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides.
3-x-5x=0
According to the distributive property, for any numbers a, b, and c, a(b+c)=ab+ac and (b+c)a=ba+ca. Here, x is a factor of both -x and -5x.
3+(-1-5)x=0
Subtract 5 from -1 to get -6.
3+(-6)x=0
Remove the parentheses.
3-6x=0
Since 3 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 3 from both sides.
-6x=-3
Divide each term in the equation by -6.
-(6x)/(-6)=-(3)/(-6)
Move the minus sign from the denominator to the front of the expression.
-(-(6x)/(6))=-(3)/(-6)
Cancel the common factor of 6 in -(6x)/(6).
-(-( 6 x)/( 6 ))=-(3)/(-6)
Remove the common factors that were cancelled out.
-(-x)=-(3)/(-6)
Multiply -1 by the -x inside the parentheses.
-1*-x=-(3)/(-6)
Multiply -1 by -x to get x.
x=-(3)/(-6)
Move the minus sign from the denominator to the front of the expression.
x=-(-(3)/(6))
Cancel the common factor of 3 in -(3)/(6) since -(3)/(6)=((-1*3))/((2*3)).
x=-(-( 3 )/(2 6 ))
Remove the common factors that were cancelled out.
x=-(-(1)/(2))
Multiply -1 by the -(1)/(2) inside the parentheses.
x=-1*-(1)/(2)
Multiply -1 by -1 to get 1.
