For the synthetic division, you first put the coefficients on the right side. This rules out A and B. Then, you take the opposite of the bottom. So it says x+5, do it with -5, so the answer is C.
Answer: A)x²+x-6 B) 2x²-13
Step-by-step explanation: A) (x+3)(x-2)(x-8) = x²-2x+3x-6 = x²+x-6
B) (x+2)(x-2)(x+3)(x-3) =→ x²-2x+2x-4 = x²-4
→x²-3x+3x-9 = x²-9
∴x²-4+x²-9 = <u><em>2x²-13</em></u>
By PEMDAS (or any alternative), <em>the first step should be to divide</em>, as D comes before A. So, 16 ÷ 4.
Hey the solution to your question is (5,10).
The compare them by by average and deviation, or you minus the 75.5 by the 10.2, 75.5-10.2= the standard average
