What is the factored form of 8x^24-27y^6

zalisa [80]

Factoring: $8x^{24}-27y^6$

Theory : A difference of two perfect cubes, $a^3-b^3$ can be factored into

$(a-b)*(a^2+ab+b^2)$

Proof : $(a-b)*(a^2+ab+b^2)=$

$a^3+a^2b+ab^2-ba^2-b^2a-b^3=$

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

$a^3+0+0+b^3=$

$a^3+b^3$

Check : 8 is the cube of 2

Check : 27 is the cube of 3

Check : $x^{24}$ is the cube of $x^8$

Check : $y^6$ is the cube of $y^2$

Factorization is :

$(2x^8 - 3y^2)*(4x^{16} + 6x^8y^2 + 9y^4)$

The functions f and g are defined as follows f(x)=-5x-3 g(x)=2x^3+2 <br> Find f(6) and g(-3)

levacccp [35]

Answer

f(6) = -33 and g(-3) = -52

Explanation;

Given the function

f(x)=-5x-3

f(6)=-5(6)-3

f(6) = -30 -3

f(6) = -33

Similarly if g(x)=2x^3+2

g(-3)=2(-3)^3+2

g(-3) = 2(-27)+ 2

g(-3) = -54 + 2

g(-3) = -52

Hence f(6) = -33 and g(-3) = -52
