Question

f(x)=2-11x+2x² polynomial function in standard form​

Answer 1

Resposta:

Oie!!!

Explicação passo-a-passo:

$2x^{2} -11x+2=0\\\\\Delta=b^2-4ac\\\\\Delta=(-11)^2-4\centerdot2\centerdot2\\\\\Delta=121-16\\\\\boxed{{\Delta=105}}\\\\\\x=\dfrac{-b\pm \sqrt{\Delta} }{2a} \\\\\\x=\dfrac{-(-11)\pm \sqrt{105} }{2\centerdot2} \\\\\\x'=x''=\boxed{\dfrac{11\pm \sqrt{105} }{4} \\\\}\\\\\\\\Bom\ final\ de\ semana!$
