Question

Me ajudemmmm!!!$\frac{(x+3) (x+5)}{8} = - \frac{7}{4} - \frac{x(x+2)}{2}$

Answer 1

(x + 3) (x + 5) / 8 = - 7 / 4 - x (x + 2) / 2
x² + 5x + 3x + 15 / 8 = - 7 / 4 - x² - 2x / 2
x² + 8x + 15 / 8 = - 7 - x² - 2x / 8
x² + 8x + 15 = - 7 - x² - 2x 
x² + 8x + 15 + 7 + x² + 2x = 0
x² + x² + 8x + 2x + 15 + 7 = 0
2x² + 10x + 22 = 0
