Anestetic [448]

Answer:

Step-by-step explanation:

Using the definition

n $C_{r}$ = $\frac{n!}{r!(n-r)!}$

where n! = n(n - 1)(n - 2) × 3 × 2 × 1

and 0! = 1

3 $C_{3}$

= $\frac{3!}{3!(3 - 3)!}$

= $\frac{3!}{3!(0!)}$

= $\frac{3!}{3!}$ = 1

Which of the following shows the factors of 5x2 + 17x + 6? A. (5x + 1)(x + 6) B. (5x + 2)(x + 3) C. (5x + 3)(x + 2) D. (5x + 6)(

zysi [14]

Answer:

B. $(x+3)(5x+2)$

Step-by-step explanation:

The given quadratic trinomial is;

$5x^2+17x+6$

Comparing this to $ax^2+bx+c$ , we have a=5,b=17,c=6.

$ac=5\times6=30$

Two factors of 30 that add up to 17 is 15 and 2.

We split the middle term to obtain;

$5x^2+15x+2x+6$

We factor by grouping;

$5x(x+3)+2(x+3)$

Factor further

$(x+3)(5x+2)$

The correct answer is B.
