1) 10w²-6w+9 = 3w²+4w+14​

Answer 1

Explicación paso a paso:

$10w ^{2} - 3 {w}^{2} - 6w - 4w + 9 - 14 = 0 \\ 7 {w}^{2} - 10w - 5 = 0$

$w = \frac{10 + - \sqrt{( - 10) ^{2} { - 4 \times 7 \times ( - 5)}} }{2 \times 10} \\ w = \frac{10 + - \sqrt{240} }{20} \\ w = \frac{10 + - 15.5}{20} \\ w = \frac{25.5}{20} \: \: \: y \: \: \: x = - \frac{5.5}{20}$
