Rearrange the terms of each equation to put it in standard quadratic form:ax^2+bx+c=0.?

1) x^2 = -6 - 5x


2) 2x + 15 = x^2


3) y^2 - 7y + 6= -4


4) 3x = 2 - 2x^3

Rearrange the terms of each equation to put it in standard quadratic form:ax^2+bx+c=0.?
just add or subtract the numbers on one side of the equation to get 0 on that side.





1) x^2 = -6 - 5x.


You need one side to be 0, so subtract the numbers from that side. Let's make the right side 0.





x^2 = -6 - 5x --%26gt;


x^2 + 5x = -6 - 5x + 5x --%26gt;


x^2 + 5x = -6 --%26gt;


x^2 + 5x + 6 = -6 + 6 --%26gt;





x^2 + 5x + 6 = 0!





you do the same thing for every problem.





Good luck!
Reply:1) add the 6 and 5


x^2+5x+6


2) subtract 2x and 15 [easier to have these negative]


x^2-2x-15


3) add the 4


y^2-7y+10


4) add 2x^3 and subtract 2


2x^3+3x-2
