The answer is 7 because you are dividing the output to the input you will get 8 for each so therefore you divide 56 by 8 to get 7
Answer:
7x^2 −12x−10
Step-by-step explanation:
((5x2 - 8x) + 1) + (2x2 - 4x - 11)
Factoring 7x2-12x-10
The first term is, 7x2 its coefficient is 7 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is -10
Step-1 : Multiply the coefficient of the first term by the constant 7 • -10 = -70
Step-2 : Find two factors of -70 whose sum equals the coefficient of the middle term, which is -12 .
-70 + 1 = -69
-35 + 2 = -33
-14 + 5 = -9
-10 + 7 = -3
-7 + 10 = 3
-5 + 14 = 9
-2 + 35 = 33
-1 + 70 = 69
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Hey there!!
Given equation :
f ( x ) = x² + 2x + 1
Find f ( 2b )
In order to solve this question, we will need to replace the value 2b instead of x
... f(2b) = ( 2b )² + 2 ( 2b ) + 1
... f(2b)= 8b² + 4b + 1
Hope my answer helps!
hope it helps..explanation..
why not just ask the question here instead? :)
