- x^2-10x+9
Answer:


Step-by-step explanation:
Given

Required
Find all product of real values that satisfy the equation

Cross multiply:


Subtract 7 from both sides


Reorder

Multiply through by -1

The above represents a quadratic equation and as such could take either of the following conditions.
(1) No real roots:
This possibility does not apply in this case as such, would not be considered.
(2) One real root
This is true if

For a quadratic equation

By comparison with 



Substitute these values in 


Add 56 to both sides


Divide through by 4

Take square roots


Hence, the possible values of r are:
or 
and the product is:


Do you have a picture or sum?
Answer: the answer is 3/48
Answer:
False
Step-by-step explanation:
10 – [50 ÷ (-2 x 25) -7] x 22 = -18
10 - (50 ÷ (-50)-7) x 22= -18
10 - (-1 - 7) x 22= -18
10 - (-8) x 22 = -18
10 + 8 x 22 = -18
10+176=-18
186=-18
False
