The factorization of 8x3 – 125 is (2x – 5)(jx2 + kx + 25). What are the values of j and k

Inga [223]

Answer:

$j=4\\k=10$

Step-by-step explanation:

$8x^3 - 125$

$\left(2x\right)^3-5^3$

Use this formula:

$x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)$

Where,

$x=2x\\y=5$

Substitute in the values.

$\left(2x\right)^3-5^3=\left(2x-5\right)\left(2^2x^2+5\cdot \:2x+5^2\right)$

$\left(2x-5\right)\left(4x^2+10x+25\right)$

Tina is attempting to factor the expression 10x^2-13-3. In her first step, she rewrites the expression as 10x^2-10x-3x-3. Which

Setler79 [48]

ANSWER

B. The two middle coefficients add to the correct number but do not multiply to the correct number.

EXPLANATION

The given quadratic trinomial that Tina tries to factor is

$10 {x}^{2} - 13x - 3$

Comparing to

$a{x}^{2} + bx + c$

we have a=10, b=-13 and c=-3

ac=-3×10=-30

We split the middle term so that their sum is -13.

Tina use

-10,-3

to get

-10x-3x

The sum is -13x alright but the product is not -30.

B is correct.

Liula [17]

Answer:

Step-by-step explanation:

3/24 = 3/3*8 = 1/8

24/32 = 4*6/4*8 = 6/8

32/24 = 4*8/4*6 = 8/6

24/3 = 3*8/3 = 8/1 = 8
