Answer:
81
Step-by-step explanation:
Given the expression: [tex]x^2+18x[/tex]
To make it a perfect square, we follow the following steps.
Divide the coefficient of x by 2
Square It
Add it to the expression
This is written as a perfect square as: [tex](x+9)^2[/tex]
The constant term required therefore is 81.
Answer:
This is written as a perfect square as [tex](x+9)^2[/tex]
The constant term required therefore is 81.
Step-by-step explanation:
Given that;
The expression [tex]x^2+18x[/tex]
we follow the following steps.
Divide the coefficient of x by 2
Coefficient of
[tex]x = 18, \\\\18 \div2=9[/tex]
Square 9
9² = 81
The expression goes
[tex]x^2+18x+81[/tex]
This is written as a perfect square as [tex](x+9)^2[/tex]
The constant term required therefore is 81.
