Explicación paso a paso:

$5x^2+25x-70=0\\\\x_{1,\:2}=\frac{-25\pm \sqrt{25^2-4\cdot \:5\left(-70\right)}}{2\cdot \:5}\\\\x_{1,\:2}=\frac{-25\pm \:45}{2\cdot \:5}\\\\x_1=\frac{-25+45}{2\cdot \:5},\:x_2=\frac{-25-45}{2\cdot \:5}\\\\x=2,\:x=-7$

☁️Hola☁️

$5 {x}^{2} + 25x - 70 = 0 \\ 5( {x}^{2} + 5x - 14) = 0 \\ {x}^{2} + 5x - 14 = 0 \\ x = \frac{ - 5 ± \sqrt{ {5}^{2} - 4 \times 1( - 14)} }{2 \times 1} \\ x = \frac{ - 5 + 9}{2} \\ x = \frac{ - 5 - 9}{2} \\ x = 2. \: \: x = - 7$
