That one, there!
When x = -3
The question gives an expression, not an equation. An expression cannot have a solution.
Well that's easy put the three in place of the "X" and add or what ever it says
Expression
1
The expression is: (4a+b)/(2a-5b)
The expression written in the question is the rational expression.
4 over x plus 3
There is no rational factorisation to this expression.
The expression has no rational factors.
(3x2 + 2x + 1)
100/(6+w)
You cannot since the expression does not have rational roots.
When x = -3
6+3*n
The expression is: y/5 plus 7
3 + (8/4) = 5
