Answer 1

Answer:

$5x {}^{2} - 7x + 2$

$5x {}^{2} - 5x - 2x + 2$

$5x(x - 1) - 2(x - 1)$

$(5x - 2)(x - 1)$

$x = \frac{2}{5} and \: x = 1$

$\alpha = \frac{2}{5} \: \: \: \: \beta = 1$

$\frac{1}{ \alpha } + \frac{1}{ \beta }$

$\frac{5}{2} + 1$

$\frac{7}{2}$

I hope this answer may help you dear

Answer 2

5x²-7x+2=0

5x² -5x-2x +2 =0

5x(x-1)-2(x-1) =0

5x-2 =0 and x-1=0

x= 2/5 and x= 1
