To write the equation 7x2 = -19 - 5x + 5x2 in standard form, we need to arrange the terms so that the powers of x decrease from left to right.
First, let's move all the terms to one side of the equation:
7x2 - 5x2 + 5x = -19
Now, let's combine the like terms:
2x2 + 5x + 19 = 0
This is the standard form of the equation.
