Question

I juat need this one can you jelp me solve it?

Answer 1

The given quadratic expression is,

`\begin{gathered} x^2+9x+35 \\ =\lbrace x^2+2(x)*(9)/(2)+((9)/(2))^2\rbrace-((9)/(2))^2+35 \\ =\lbrace x^2+2(x)*(9)/(2)+((9)/(2))^2\rbrace-(81)/(4)^{}+35 \\ =\lbrace x^2+2(x)*(9)/(2)+((9)/(2))^2\rbrace-(81)/(4)^{}+35 \\ =\lbrace x^2+2(x)*(9)/(2)+((9)/(2))^2\rbrace+(-81+140)/(4)^{} \\ =\lbrace x^2+2(x)*(9)/(2)+((9)/(2))^2\rbrace+(59)/(4)^{} \end{gathered}`

Thus, 81/4 must be added to complete
