Question

m² - 2m=2 /by quadratic equation​

Answer 1

Answer:

(2 + ✓12 ) ÷ 2

(2 + ✓12 ) ÷ 2 or

(2 + ✓12 ) ÷ 2 or( 2- ✓12 ) ÷ 2

Step-by-step explanation:

m² - 2m = 2

m² - 2m - 2 = 0

where,

a = 1

b = -2

c = -2

Using Quadratic formula

(-b ± ✓b² - 4ac) ÷ 2a

b² - 4ac

= (-2)² - 4 × 1 × (-2)

= 4 + 8

= 12

(-(-2) ± ✓12) ÷ 2

( 2 ± ✓12) ÷ 2

ie, zeroes of the polynomial

= (2 + ✓12 ) ÷ 2

or

= ( 2- ✓12 ) ÷ 2
