Question

find the discrimnant of x^2+10x-7=0 be fast

Answer 1

Answer:

x²+ 10x - 7 = 0

a = 1 , b = 10 , c = -7

∆ = b²- 4ac

∆ = (-10)²- 4(1)(-7)

∆ = 100 + 28

∆ = 128

∆ > 0

Thank you dishu

Answer 2

Answer:

Hi friend ⭐♥️❣️

$x {}^{2} + 10x - 7 \\ d = b {}^{2} - 4ac \\ = 10 {}^{2} -( 4 \times 1 \times -7) \\ = 100 +28 \\ = 128 \\ roots \: are \: real \: and \: distinct$

a=1. b= 10 c= -7
