Question

Determine the nature of roots of equation x² +3x+4=0 equation​

Answer 1

${x}^{2} + 3x + 4 = 0 \\ \\ a = 1 \: \: \: b = 3 \: \: \: c = 4 \\ \\ {b }^{2} - 4ac = ( {3}^{2} ) - 4 \times 1 \times 4 \\ 9 - 16 \\ 7 \\ {b}^{2} - 4ac = 7 \\ real \: and \: not \: equal$

these is your answer..........friend
