Question

ayuda lo necesitopor favor alguien que me ayude​

Answer 1

Explicación paso a paso:

•

$60 = 8 {x}^{2} + 157x \\ - 8 {x}^{2} - 157x + 60 = 0 \\ 8 {x}^{2} + 157x - 60 = 0$

•

$x(x - 1) - 5(x - 2) = 2 \\ {x}^{2} - x - 5x + 10 = 2 \\ {x}^{2} - 6x + 8 = 0$

•

$\frac{(y + 2)}{y} + y = \frac{74}{y} \\ (y + 2) + {y}^{2} = 74 \\ {y}^{2} + y - 72 = 0$

•

${(y + 2)}^{2} - \frac{(2y - 5)}{3} = 3 \\ 3( {y}^{2} + 4y + 4) - (2y - 5) = 9 \\ 3 {y}^{2} + 12y + 12 - 2y + 10 = 9 \\ 3 {y}^{2} + 10y + 13 = 0$
