Find the zeros of the quadratic function. Solve by factoring. x^2+14x=-45

Reptile [31]

So, x^2 + 14 x + 49 - 4 = 0;

Then, we use the formula ( a + b )^2 = a^2 + 2ab + b^2;

We have ( x + 7 )^2 - 2^2 = 0;

Then, ( x + 7 )^2 - 2^2 = 0;

We use the formula a^2 - b^2 = ( a - b)( a + b );

We obtain ( x + 5 )( x + 9) = 0;

Then, x + 5 = 0;

x = -5;

x + 9 = 0;

x = - 9;

-5 and - 9 are the zeros of the quadratic function.

Find the taylor polynomial t3(x) for the function f centered at the number

olga nikolaevna [1]

$e^{-4x}=\displaystyle\sum_{n=0}^\infty\frac{(-4x)^n}{n!}=1+(-4x)+\dfrac{(-4x)^2}2+\dfrac{(-4x)^3}6+\cdots$
$e^{-4x}=1-4x+8x^2-\dfrac{32x^3}3+\cdots$

$\sin2x=\displaystyle\sum_{n=0}^{\infty}\frac{(-1)^k(2x)^{2k+1}}{(2k+1)!}=(2x)-\dfrac{(2x)^3}6+\cdots$
$\sin2x=2x-\dfrac{4x^3}3+\cdots$

$e^{-4x}\sin2x=\left(1-4x+8x^2-\dfrac{32x^3}3+\cdots\right)\left(2x-\dfrac{4x^3}3+\cdots\right)$
$e^{-4x}\sin2x=2x-8x^2+\dfrac{44x^3}3+\cdots$

$\implies T_3(x)=2x-8x^2+\dfrac{44x^3}3$

X+20+x+8+2x+12=180

4x+40=180

4x=140

x=35
