Which is different? Find "both" answers. Find AC+CB.

Find BC−AC.

Find AB.

Find CA+BC.

Question 2

The "different" answer is

. The "same" answer is

.

Step-by-step explanation:

Question 1

BC - AC and AB will provide different answers when compared to AC + CB and CA + BC. This is because AC means A multiplied by C (AC) or C multiplied by A (CA); thus means AC and CA are the same. Also, CB means C multiplied by B (CB) or B multiplied by C (BC); thus means CB and BC are the same.

Hence, Finding AC + CB will provide the same answer as finding CA + BC

However, finding BC - AC will provide different answer to finding AB because BC - AC means the multiplication of A and C is subtracted from the multiplication of B and C - the answer thereof will most likely be different from the multiplication of just A and B.

Question 2

From the explanation above,

The "different" answer is

Find BC - AC  and Find AB

The "same" answer is

Find AC + CB and Find CA + BC

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
