Question

find the value of the discriminant of the equation X² + 10 x - 7 =0​

Answer 1

Answer:

128

Step-by-step explanation:

discriminant(∆)=b^2-4ac

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

∆=100-4(1)(-7)

=100+28

=128

Answer 2

Answer :-128

solution:- Comparing x²+10x-7=0

with ax² +bx+C =0.

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

b² -4 ac = 10²-4(1)(-7)

=100+28

=128
