(x+8)² expressed as a trinomial in standard form

Citrus2011 [14]

Answer:

x² + 16x + 64

Step-by-step explanation:

(a + b)² = a² + 2ab + b²

Here, a = x & b = 8

(x+8)² = x² + 2*x*8 +8²

= x² + 16x + 64

Suppose that f(1=9, f(4=?3, f?(1=9, f?(4=?5, and f?? is continuous. find the value of ?41xf??(xdx.

Over [174]

Some characters in your question are not displayed properly, so I'm guessing at what it says.

"Suppose that $f(1)=9$ , $f(4)=-3$ , $f'(1)=9$ , $f'(4)=-5$ , and $f''$ is continuous. Find the value of $\displaystyle\int_1^4xf''(x)\,\mathrm dx$ ."

(Correct me if I'm wrong!)

Integrate by parts, letting $u=x$ and $\mathrm dv=f''(x)\,\mathrm dx$ , so that $\mathrm du=\mathrm dx$ and $v=f'(x)$ . Then you have

$\displaystyle\int_1^4xf''(x)\,\mathrm dx=xf'(x)\bigg|_{x=1}^{x=4}-\int_1^4f'(x)\,\mathrm dx$

Integrating once more gives

$\displaystyle\int_1^4xf''(x)\,\mathrm dx=xf'(x)\bigg|_{x=1}^{x=4}-f(x)\bigg|_{x=1}^{x=4}$
$=(4f'(4)-1f'(1))-(f(4)-f(1))$
$=(-20-9)-(-3-9)=-17$
