Answer:
First Blank: 5
Second Blank: 5
Third Blank: -1
Fourth Blank: -1
Fifth Blank: 3
Step-by-step explanation:
10x+15y=15
-10x+2y=-32
__________
17y=-17
__ ___
17 17
y=-1
2x+3(-1)=3
2x-3=3
+3 +3
________
2x=6
__ __
2 2
x=3
I don't think the numbers exist. 6 and 2 don't work because 6 * 2 does not equal 8. If you were solving a quadratic equation by factoring and you needed to find the two numbers, and you can't find them, you can solve the quadratic equation by using the quadratic formula.
9x9=81
8x9=72
9x9=81
-9x9=-81
Answer:
B. −2
C. −1
E. 1
Step-by-step explanation:
He have been given a polynomial function 
. We are asked to find the zeros of our given function.
To find the zeros of our given function, we will equate our function with zero and solve for x as:
Now, we will factor our equation by grouping method.
Now, we will use difference of squares 
Using zero product property, we will get:
Since the zeros of our given function are 
, therefore, options B, C and E are correct choices.
