Recognize sum of cubes: Recognize the expression as a sum of cubes.The given expression is of the form a3+b3, where a3 is 64y3 and b3 is 27h3. The sum of cubes can be factored using the formula a3+b3=(a+b)(a2−ab+b2).
Identify values of 'a' and 'b': Identify the values of 'a' and 'b'.In the expression 64y3+27h3, we can see that a3=64y3 and b3=27h3. To find 'a' and 'b', we take the cube root of each term.a=(64y3)1/3=4yb=(27h3)1/3=3h
Apply sum of cubes formula: Apply the sum of cubes formula.Using the values of 'a' and 'b' from Step 2, we apply the sum of cubes formula:64y3+27h3=(4y+3h)((4y)2−(4y)(3h)+(3h)2)
Expand and simplify terms: Expand and simplify the terms in the factorization.Now we calculate each term in the formula:(4y)2=16y2(4y)(3h)=12yh(3h)2=9h2So the factorization becomes:64y3+27h3=(4y+3h)(16y2−12yh+9h2)
Write final factorized form: Write the final factorized form.The completely factorized form of the expression is:64y3+27h3=(4y+3h)(16y2−12yh+9h2)
