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

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
