Write the following quadratic expression in vertex form x^2+4x+10

9514 1404 393

  (x +2)^2 +6

Step-by-step explanation:

We can add and subtract the square of half the x-coefficient.

  x^2 +4x +10 = (x^2 +4x +2^2) +10 -2^2

  = (x +2)^2 +6

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
