Explanation:

Set the next factor equal to 0 0 . Subtract 5 5 from both sides of the equation. Divide each term by 2 2 and simplify. Divide each term in 2x=−5 2 x = - 5 by 2 2 .

\therefore \frac{a+2}{\beta+2}+\frac{\beta+2}{a+2}=\frac{13}{6}

விளக்கம்:

\frac{a+2}{\beta+2}+\frac{\beta+2}{a+2}

மீ.பொ.ம = (\alpha+2)(\beta+2)

\frac{3(a+2)^{2}+(\beta+2)^{2}}{(a+2)(\beta+2)}

=\frac{a^{2}+4 a+4+\beta^{2}+4 \beta+4}{(a+2)(\beta+2)}

=\frac{\alpha ^{2}+4\alpha+4+\beta^{2}+4 \beta+4}{(\alpha+2)(\beta+2)}

=>\frac{\left(\alpha ^{2}+\beta^{2}\right)+4(\alpha+\beta)+8}{\alpha \beta+2(\alpha+\beta)+4}

2 x^{2}-7 x+5=0

a=2, b=-7, c=5

\alpha+\beta=-b / a=-(-7) / 2=7 / 2

\alpha \beta=c / a=5 / 2

=\frac{(\alpha+\beta)^{2}-2\alpha \beta+4(\alpha+\beta)+8}{\alpha \beta+2(\alpha+\beta)+4}

=\frac{(7 / 2)^{2}-2(5 / 2)+4(7 / 2)+8}{5 / 2+2(7 / 2)+4}

=\frac{49 / 4-5+14+8}{5 / 2+7+4}

=\frac{49 / 4-5+22}{5 / 2+11}

=\frac{49 / 4+17}{5 / 2+11}

=>\frac{49+68 / 4}{5+22 / 2}

=>\frac{117 / 4}{27 / 2}

=117 / 4 \times 2 / 27

\therefore \frac{a+2}{\beta+2}+\frac{\beta+2}{a+2}=\frac{13}{6}
