Question

Transform the following equations into standard form
1. x^2 + 2x = -1
2. 4 + x^2 = 7x
3. x^2 - x = 1
4. x^2 + 9x = 10
5.4x + 3 = x^2
6. x^2 + 5x +5
7. 2x^5 + 7x = 3x
8. x^2 = 3x + 8
9. x(x + 3) = 1
10. x^2 - 3x = -2
11. y^2 - 7y = -6
12.z^2 - 5z = -4


Some one please help I don't understand what I'm supposed to do

Answer 1

I think they want the equation in the form
ax^2 + bx + c = 0, where a is a positive real number

so just "move" all the terms to the left side and set them equal to zero

e.g. #5
4x + 3 = x^2
-x^2 + 4x + 3 = 0
x^2 - 4z - 3 = 0

Do the others the same way, it is really quite easy.
