For x = 5 and y = 2 , verify
( x + y )³ = x³ + y³ + 3x²y + 3xy²​

Answer 1

Answer:

SEE THE EXPLANATION

Step-by-step explanation:

(5+2)³=5³+2³+3(5)²2+3(5)2²

LHS

(5+2)²=7³=343

RHS

5³+2³+3(5)²2+3(5)2²

125+8+3(25)2+15(4)

133+150+60

133+210

343

Answer 2

Question

For x = 5 and y = 2 , verify ( x + y )³ = x³ + y³ + 3x²y + 3xy²

Given:

• x=5
• y=2

To find

• ( x + y )³ = x³ + y³ + 3x²y + 3xy²

Step by step explanation

( x + y )³ = x³ + y³ + 3x²y + 3xy² (i)

putting the value of x and y in equation (i)

(5+2)³= 5³ + 2³ + 3×5²×2 + 3×5×2²

7³= 125 + 8 + 150 + 60

343= 133 +210

343= 343

LHS=RHS
