Question

2x2-15x+17=x2-8x+11 me ayudan a resolver esta ecuación

Answer 1

$2x^2-15x+17=x^2-8x+11$
$2x^2-15x+17-x^2+8x-11=0 x^2-7x+6=0$
$x= \frac{-(-7)+- \sqrt{(-7)^2-4*1*6} }{2*1}$
$x= \frac{7+- \sqrt{49-24} }{2}$
$x= \frac{7+- \sqrt{25}}{2}$
$x= \frac{7+-5}{2}$
$x_{1} = \frac{7+5}{2} = \frac{12}{2}$
$x_{2} = \frac{7-5}{2}= \frac{2}{2}$
$x_{1} =6$
$x_{2} =1$
