How do you find the sum of cube ?

SIZIF [17.4K]

Answer:

$(2x+5)(4x^{2} -10x+25)=0$

Step-by-step explanation:

Given:

The given equation is.

$8x^{3} +125=0$

Find the some of cube.

Solution:

$8x^{3} +125=0$

$2^{3}x^{3} +5^{3}=0$

$(2x)^{3} +5^{3}=0$ ----------(1)

The sum of the cube formula is given below.

$(a^{3} +b^{3})=(a+b)(a^{2} -ab+b^{2} )$ -----------(2)

By comparing equation 1 and equation 2

$a=2x, b=5$

substitute a and b value in equation 2

$((2x)^{3} +5^{3})=(2x+5)((2x)^{2} -(2x)(5)+5^{2})$

$((2x)^{3} +5^{3})=(2x+5)(4x^{2} -(10x)+25)$

$((2x)^{3} +5^{3})=(2x+5)(4x^{2} -10x+25)$

Therefore the sum of the cube $(2x+5)(4x^{2} -10x+25)=0$

Whats 2x2+34x24+3x0+1x400x100x456x0

aivan3 [116]

Answer:

820

Step-by-step explanation:

If you use order of operations, you can find that 3x0 and 1x400x100x456x0 is just 0 so you just have to add 2x2 and 34x24. Which is 820

order of operations is

GEMDAS

Grouping symbols

exponents

multiplication and division (these don't have to be in order)

Addition and Subtraction (again, these don't have to be in order)
