STR and QTP are both equal 180
so PTS +PTR=180 andQTR+PTR=180 which means
PTS=QTR(for a shorter explanation they are staying against each other in a line cross
11y-110=4y-5
7y=105
y=105:7
y=15 grafe which means
PTS
y*4-5=55 grade

Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
Step-by-step explanation:
The equation
can be solved by squaring both sides:

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

The square root of 49 equals 7, but the square root of -1 is an imaginary number.
The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
ANSWER
A. -3, -2, 2, and 3
EXPLANATION
The given polynomial function is,

To find the real roots, we equate the function to zero to obtain;

We can solve this equation as a quadratic equation in

Thus we rewrite the equation as,

We split the middle term to get,

We factor to get,

We factor to get,

Either

or




The correct answer is A
