Question

Solve it plz!!!!!!!!!!​

Answer 1

Answer:

Given

x ^{2} + 7x - 1 = 0x

2

+7x−1=0

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

since

b ^{2} - 4acb

2

−4ac

is the discriminant of quadratic equation

so 7^2 - 4×1×(-1) = 49+4 = 53.

Answer 2

Answer:

Given

x^2+7x-1=0

Explanation:

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

since b^2-4ac

is the discriminant of quardractic equation

So 7^2-4×1(-1)=49+4=53
