Answer:

23x^2

Step-by-step explanation:

When adding variables, if they have the same exponent then all that needs to be done is add the constants. In this case both have x^2 so the answer is 23x^2. Hope this helps! :)

5(x+3)(x+2)-3(x2+2x+1)
mr Goodwill [35]

[ Answer ]

\boxed{5x^{2} \ + \ 13x \ + \ 27}

[ Explanation ]

  • Simplify: 5(x + 3)(x + 2) - 3(x2 + 2x + 1)

--------------------------------------

  • Add Similar Elements: 2x + 2x = 4x

5(x + 3)(x + 2) - 3(4x + 1)

  • Expand: 5(x + 3)(x + 2) - 3(4x + 1): 5x^{2} + 25x + 30

5x^{2} + 25x + 30 - 3(4x + 1)

  • Expand: - 3(4x + 1): -12x - 3

5x^{2} + 25x + 30 - 12x - 3

  • Simplify: 5x^{2} + 25x + 30 - 12x - 3: 5x^{2} + 13x + 27

= 5x^{2} + 13x + 27

\boxed{[] \ Eclipsed \ []}

2) 62 - 46 +4 = 0 <br> quadratic formula
AleksandrR [38]

This does not need the quadratic formula since there are no variables to begin with:

62-46+4 = 0

20 = 0.

And 20 does not equal 0 so both sides aren't equal.

Soooo not much to do with this question.
