Question

Find nature of roots 3x2 +5x-7=0

Answer 1

$\huge\pink{Answer\: is}$

$3x {}^{2} + 5x - 7 = 0$
Here.
a = 3
b = 5
c = -7

$= b {}^{2} - 4 a c \\ = 5 {}^{2} - 4 \times 3 \times ( - 7) \\ = 25 + 84 \\ = 109 \\ as \: b {}^{2} - 4ac \: > 0 \\ then \: \\ roots \: are \: real \: and \: unequal$
