Question

x2 + 7x - 1 = 0 FIND THE VALUE DISCREMINATE​

Answer 1

Answer:

discriminant= 53

Explanation:

Given equation is x²+7x−1=0

Discriminant=D=b²−4ac

where a=1,b=7 and c=−1

∴D= 7²–4(1)(-1)

= 49+4

= 53

53>0

D>0

Answer 2

Explanation:

x²+7x-1=0

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

D=b²-4ac

=(7)²-4*1*-1

=49+4

=53

there fore 53>0,

D>0

the roots will be real
