Answer:

1 * 10^12

Step-by-step explanation:

Scientific notation is a representation of a large number in a short form. The answer, 1*10^12 (read as ten to the twelfth power) essentially says that the number when expanded is 1 with 12 zeros appended to it. If you did a number like 7 trillion you would have 7 * 10^12.

Same thing can be applied for 1,000,000 (one million).

1 * 10^6 because one million has 6 zeros appended to it.

Find p(0),p(1),p(-1) and p(2) of the 3x(x-2) <br><br>

Effectus [21]

Answer:

<u>make x→0</u>

$p(0)=(0)^{2}-3(0)+2$

→ $p(0)=0+0+2$

→ $p(0)=2$

$------$

<u>Replace x→-1</u>

$p(-1)=(-1) ^{2} -3 (-1)+2$

→ $p(-1)=1-3+2$

→ $p(-1)=0$

$----------$

<u>Now make x→2</u>

$p(2)=(2) ^{2} -3(2)+2$

→ $p(2)=4-6+2$

→ $p(2)=0$

$Answer:-2,0,0$

$-----------$

hope it helps...

have a great day!!

Polynomial equation when zeros are -4, -2, 1, 4

jek_recluse [69]

<h2>The required poynomial equation is $x^{4}+x^{3}-18x^{2}-16x+32$ .</h2>

Step-by-step explanation:

Given,

The zeros of the polynomial are - 4, - 2, 1 and 4

To find, the polynomial equation = ?

We know that,

The polynomial equation = (x - A)(x - B)(x - C)(x - D)

= (x + 4)(x + 2)(x - 1)(x - 4)

= [(x + 4)(x - 4)] [(x + 2)(x - 1)]

= ( $x^{2}-16$ )( $x^2-x+2x-2$ )

= ( $x^{2}-16$ )( $x^2+x-2$ )

= $x^{4}+x^{3}-2x^{2}-16x^{2}-16x+32$

= $x^{4}+x^{3}-18x^{2}-16x+32$

Thus, the required poynomial equation is $x^{4}+x^{3}-18x^{2}-16x+32$ .
