Question

19. If the roots of the equation 2x²+x+3=0 are equal, then find the valu.
of 'k'​

Answer 1

Step-by-step explanation:

$2 {x}^{2} + x + 3 = 0 \\ a = 2 \\ b = 1 \\ c = 3 \\ \\ so \: \: \: \\ {b}^{2} - 4(a)(c) \\ {1}^{2} - 4(2)(3) \\ 1 - 24 \\ - 23 \\ \\ \\ \\ so \\ - b \frac{ + }{ - } \sqrt{ - 23} \div 2(2) \\ \\ - 1 \frac{ + }{ - } \sqrt{ - 23} \div 4$
