What number must you add to the polynomial below to complete the square? x^2+17x

Juliette [100K]

The number added to the polynomial by completing the square is $\frac{289}{4}$

Explanation:

Given that the polynomial is $x^{2} +17x$

We need to determine the number that is added to the polynomial to complete the square.

The last term of the polynomial can be determined by dividing the term 17 by 2 and then squaring the term.

Thus, we have,

Last term = $\frac{17}{2}$

Now, squaring the term, we have,

Last term = $(\frac{17}{2})^2=\frac{289}{4}$

Thus, the number added to the polynomial by completing the square is $\frac{289}{4}$

Solve the inequality. Graph the solution +5<2 The solution is a 6

BartSMP [9]

Answer:

x<-3

The graph in the attached figure

Step-by-step explanation:

The correct question is

Solve the inequality. Graph the solution.

x+5<2

we have

$x+5$

Solve for x

Subtract 5 both sides

$x$

The solution is the interval (-∞,-3)

All real numbers less than -3

In a number line, the solution is the shaded area at left of x=-3 (open circle)

The number x=-3 is not included in the solution
