Answer:
38
Step-by-step explanation:
the equation to find discriminant is b-4ac
the equation to find discriminant is b-4acthen, the values are a=1,b=10 and c=-7
according to given equation,
according to given equation,b-4ac
according to given equation,b-4ac=10-4×1×(-7)
according to given equation,b-4ac=10-4×1×(-7)=10-(-28)
according to given equation,b-4ac=10-4×1×(-7)=10-(-28)=38
