What are the zeroes of f(x) = x2 + 5x + 6?

photoshop1234 [79]

Here is your answer

a) x=-2, -3

REASON :
$f(x)= {x}^{2}+5x+6$

= ${x}^{2}+2x+3x+6$

= $x(x+2)+3(x+2)$

= $(x+2)(x+3)$

To find zeroes

f(x)= 0

So,

(x+2)(x+3)=0

$x=-2 or x=-3$

Divide x^4+3x^3-2x^2+4 by x-2<br><br>which answer shows the correct synthetic division and quotient

arsen [322]

Answer:

option-A

$\frac{x^4+3x^3-2x^2+4}{x-2}=x^3+5x^2+8x+16+\frac{36}{x-2}$

Step-by-step explanation:

we are given

divisor is

$=x^4+3x^3-2x^2+4$

Dividend is

=x-2

so, we can use synthetic division

so, we can write our expression as

$\frac{x^4+3x^3-2x^2+4}{x-2}=x^3+5x^2+8x+16+\frac{36}{x-2}$
