$⟹</p><p>2 {x}^{2} - x + 1 = 0$

$⟹</p><p>2 {x}^{2} - 2x + x + 1 = 0$

$⟹</p><p>2x(x - 1) - 1(x - 1) = 0$

$⟹</p><p>(2x - 1)(x - 1) = 0$

$⟹</p><p>2x - 1 = 0$

$⟹</p><p>x = \frac{1}{2}$✓

$⟹</p><p>x - 1 = 0$

$⟹</p><p>x = 1$✓

Answer 2

Step-by-step explanation:

=2x^2-2x+x+1

2x(x-1)-1(x-1)

(2x-1)(x-1)

x=1/2

x=1

the roots of polymial is 1&1/2
