Question

The quadratic equation whose roots are 1 and

(a) 2x² + x – 1 = 0

(b) 2x² – x – 1 = 0​

Answer 1

Answer:

$2( {1}^{2} ) + 1 - 1 = 0$

$3 - 1 = 0$

$2 = 0$

$2 \: not \: equal \: to \: 0$

2-2=0

2-1-1=0

so option b

Answer 2

Answer:

The quadratic equation whose roots are 1 is *

1 point

2x² - x + 1 = 0

2x² + x – 1 = 0

2x² + x + 1 = 0

2x² - x – 1 = 0
