7 + 4x - 10x + 15 = 22 - 6x
You just need to sum terms of polynomial with the same stage of x and not to mix them out. Note that terms without x are actually terms with x^0 because x^0 = 1
Therefore we sum 7 and 15 = 22 and
we sum 4x and -10x = -6x
Answer is B)
Answer:
x^3-2x^2-13x+6
Step-by-step explanation:
We are to simplify the expression (x+3)(x^2−5x+2). This is as shown;
(x+3)(x^2−5x+2)
Expand
= x(x^2)-5x(x)+2x+3x^2-3(5x)+6
= x^3 - 5x^2+2x+3x^2-15x+6
Collect the like terms
= x^3 - 5x^2+3x^2+2x-15x=6
= x^3-2x^2-13x+6
This gives the required expression
The answer to the above question is three
Answer:
The 2 integers would be: 2 and 8
Step-by-step explanation:
2 + 8 = 10
Reciprocal of 2: 1/2
Reciprocal of 8: 1/8
1 / 2 - 1 / 8 = 4/8 - 1/8 = <u>3/8</u>
