Question

For the given quadratic equation √2 x^ 2 + 7 x+ 5 √2 = 0 (i) Find the discriminant. (ii) Comment on the nature of the roots. (iii) Find the roots.

Answer 1

Step-by-step explanation:

√2x² +7x + 5√2 = 0

a= √2 , b=7 , c=5√2

WE KNOW THAT B² - 4*AC

(7)² - 4* √2 *5√2

49 - 4 * 5 * 2

49 - 40 = 9

THEREFORE THE NATURE OF THE QUADRATIC EQUATION IS REAL AND UNEQUAL
