Answer:
-5
Step-by-step explanation:
To Solve x we can use the product rule and multiply 4 in the the brackets:
[tex]4*(2*x+10)=0[/tex]
[tex]8*x+40=0[/tex]
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:
[tex]8*x=-40[/tex]
[tex]x=-40/8=-5[/tex]
The value of x is -5
