Step-by-step explanation:
We need to write the function that have two real number zeros by calculating the discriminant i.e. .
We know that,
If D>0 the roots are real and unequal
If D= 0 roots are real and equal
If D< 0 roots are imaginary or not real and unequal
Function (1)
D>0 the roots are real and unequal
Function (2)
D<0 the roots are real and unequal
Function (3)
D>0 the roots are real and unequal
Function (4)
D>0 the roots are real and unequal
Function (5)
D<0 the roots are real and unequal
Function (6)
D>0 the roots are real and unequal
(1),(3),(4) and (6) have two real number zeroes.
Answer: X=44
Step-by-step explanation:
X + 6x = 308
Combine like terms
7x = 308
Divide both sides by 7
X = 44
They missed 44
