Answer:
The missing coefficient of the x-term of the product (-x-5)2 is 10.
Step-by-step explanation:
Through whole square formula.
(-x-5)2 = (-x)^2 -2(-x)(5)+(5)^2
=x^2+10x+25
Therefore, the missing coefficient of the x-term of the product is 10
Answer:
10
Step-by-step explanation:
The given expression is
[tex](-x-5)^2[/tex]
We need to find the coefficient of x.
According to the property of algebra.
[tex](a-b)^2=a^2-2ab+b^2[/tex]
In the given expression a=-x and b=5.
Substitute a=-x and b=5 in the above formula.
[tex](-x-5)^2=(-x)^2-2(-x)(5)+(5)^2[/tex]
On further simplification we get
[tex](-x-5)^2=x^2+10x+25[/tex]
Coefficient of x is a multiplicative factor of x.
Therefore, the coefficient of x is 10.
