Step-by-step explanation:
Answer:
Step-by-step explanation:
The given functions are:
and
We want to to find
Note that:
We substitute the functions to obtain:
We now substitute x=7, to get:
This implies that
it has no root
first make it common quadratic form
y = 5x² - 3x + 8
we take
a = 5
b = -3
c = 8
the to prove it doesn't have root. we using discriminant
D = b² - 4ac
D = (-3)² - 4*5*8
D = 9 - 160
D = - 151
D > 0 means the equation has 2 roots
D = 0 means the equation has 1 root
D < 0 do not have root because it doesn't have intercept on x-axis
