Question

find the root (if they exist) of the quadratic equation by method of complete square x²+4x-9=0​

Answer 1

x² + 4x - 9 = 0

here , a = 1 ,b = 4 , c = -9

by Discriminat formula ,

D = b² - 4ac = (4)² - 4(1)(-9)

= 16-(-36) = 16+36 = 52

D > 0 , There are no real roots for the Given Quadratic Equation

Answer 2

$\huge\bigstar\mathtt{ \color{red}{A} \color{orange}{N} \color{yellow}{S} \color{lightgreen}{W} \color{blue}{E} \color{indigo}{R}\bigstar}$
