Question

x(x-5)-2x(x+6< x2-11x porfa​

Answer 1

Respuesta:

3√−1

Explicación paso a paso:

x(x-5)-2x(x+3)+6-(x2-11x)=0

-(+x^2-11x)+x(x-5)-2x(x+3)+6=0

-(+x^2-11x)+x^2-2x^2-5x-6x+6=0

-x^2+x^2-2x^2+11x-5x-6x+6=0

-2x^2+6=0

a = -2; b = 0; c = +6;

Δ = b2-4ac

Δ = 02-4·(-2)·6

Δ = 48

x1=−b−Δ√2ax2=−b+Δ√2a

La solucion final:

Δ−−√=48−−√=16∗3−−−−−√=16−−√∗3√=43√

x1=−b−Δ√2a=−(0)−43√2∗−2=0−43√−4=−43√−4=−3√−1

x2=−b+Δ√2a=−(0)+43√2∗−2=0+43√−4=43√−4

=3√−1
