If (1)=0, what are all the roots of the function f(x)=x3+3x2-x-3?use the remainder theorem

Anon25 [30]

If $f(1)=0$ , then by the remainder theorem $\dfrac{f(x)}{x-1}$ has a remainder of 0, which means $f(x)$ is divisible by $x-1$ . In fact,

$x^3+3x^2-x-3=x^2(x+3)-(x+3)=(x^2-1)(x+3)=(x-1)(x+1)(x+3)$

So we know 1 is a root, and the other two roots are -1 and -3.

Figure ABCD is a trapezoid. Find

Rudiy27

Answer:

x = 3

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

$\frac{1}{2}$ (3x + 3 + 4x + 2) = 13

$\frac{1}{2}$ (7x + 5) = 13 ( multiply both sides by 2 )

7x + 5 = 26 ( subtract 5 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3
