Answer 2

Let's simplify each of the given expressions:

A) c(a+b) + 2c(2a+3b)

Step 1: Distribute the 'c' in the second term c(a+b) + 2c2a + 2c3b

Step 2: Simplify ca + cb + 4ac + 6bc

Step 3: Combine like terms ca + 4ac + cb + 6bc

Final simplified expression: ca + 4ac + cb + 6bc

B) (2a+5b)(3c-5d)-(2a+5d)-(2a+5d)-(2a+5b)(6c-5d)

Step 1: Distribute both terms in the first bracket (2a3c + 2a(-5d) + 5b3c + 5b(-5d)) - (2a+5d) - (2a+5d) - (2a6c + 2a(-5d) + 5b6c + 5b(-5d))

Step 2: Simplify (6ac - 10ad + 15bc - 25bd) - (2a + 5d) - (2a + 5d) - (12ac - 10ad + 30bc - 25bd)

Step 3: Combine like terms 6ac - 10ad + 15bc - 25bd - 2a - 5d - 2a - 5d - 12ac + 10ad - 30bc + 25bd

Step 4: Further simplify (6ac - 12ac) + (-10ad + 10ad) + (15bc - 30bc) + (-25bd + 25bd) - (2a + 2a) - (5d + 5d)

Step 5: More simplification -6ac + 0 + -15bc + 0 - 4a - 10d

Final simplified expression: -6ac - 15bc - 4a - 10d

C) h(3a-c+2k(c-3a))

Step 1: Distribute 'h' h3a - hc + h*2k(c-3a)

Step 2: Simplify 3ha - hc + 2hkc - 6hka

Final simplified expression: 3ha - hc + 2hkc - 6hka

D) (2a+5b)3(3c-5d)2-(2a+5b)2(6c-5d)3

Step 1: Expand both terms (2a3 + 2a(-5d) + 5b3 + 5b(-5d))^3 * (3c2 - 5d2) - (2a2 + 2a5b + 5b2)(6c3 - 5d*3)

Step 2: Simplify (6a - 10d + 15b)^3 * (6c - 10d) - (4a + 10b)(18c - 15d)

Step 3: Use the formula (a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3 (6a)^3 + 3*(6a)^2*(-10d) + 36a(-10d)^2 + (-10d)^3 * (6c - 10d) - (4a + 10b)(18c - 15d)

Step 4: Simplify the terms 216a^3 - 540a^2d + 450ad^2 - 1000d^3 * (6c - 10d) - (4a18c + 4a(-15d) + 10b18c + 10b(-15d))

Step 5: More simplification 216a^3 - 540a^2d + 450ad^2 - 1000d^3 * 6c + 1000d^4 - (72ac - 60ad + 180bc - 150bd)

Step 6: Combine like terms 216a^3 - 540a^2d + 450ad^2 - 6000d^3c + 1000d^4 - 72ac + 60ad - 180bc + 150bd

Final simplified expression: 216a^3 - 540a^2d + 450ad^2 - 6000d^3c + 1000d^4 - 72ac + 60ad - 180bc + 150bd
