Answer:
-5
Step-by-step explanation:
To Solve x we can use the product rule and multiply 4 in the the brackets:
\(4*(2*x+10)=0\)
\(8*x+40=0\)
We can move the fourty to the right hand side of the equal sign and then simplify the equation by dividing the whole expression by 8:
\(8*x=-40\)
\(x=-40/8=-5\)
The value of x is -5
