(2x - 3)(x + 5) - (3 - x)(5 - 2x) = -30
Expand each set of parentheses:
2x^2 + 10x - 3x - 15 - (15 - 3x - 5 + 2x) = -302x^2 + 7x - 15 - 15 + 3x + 5 - 2x = -302x^2 + 7x - 15 - 15 + 3x + 5 - 2x + 30 = 02x^2 + 7x + 3x - 2x - 15 - 15 + 5 + 30 = 02x^2 + 8x - 25 = 0
The above equation is now in standard form.
