hi5!!
10^2-x^2=(10+x)(10-x)
using the property that a^2-b^2=(a+b)(a-b)
so its cube is (10+x)^3(10-x)^3
1000+x^3+30x(10+x)multiplied by 1000-x^3-30x(10-x)
10^2-x^2=(10+x)(10-x)
using the property that a^2-b^2=(a+b)(a-b)
so its cube is (10+x)^3(10-x)^3
1000+x^3+30x(10+x)multiplied by 1000-x^3-30x(10-x)
10^2-x^2=(10+x)(10-x)
using the property that a^2-b^2=(a+b)(a-b)
so its cube is (10+x)^3(10-x)^3
1000+x^3+30x(10+x)multiplied by 1000-x^3-30x(10-x)
using the property that a^2-b^2=(a+b)(a-b)
so its cube is (10+x)^3(10-x)^3
1000+x^3+30x(10+x)multiplied by 1000-x^3-30x(10-x)
