Question

5x+5x=6. Prove R.H.S = L.H.S​

Answer 1

Answer:

2+2=4

2+2 = 4 + 9/2 - 9/2 //add and subtract 9/2

2+2 ={ √(4- 9/2)² } + 9/2 //square root and whole square

2+2 = { √ 16 - 36 + (9/2)² } + 9/2 // open the whole square in the root

2+2 = { √ -20 + (9/2)² } + 9/2

2+2 = { √ 25–45 + (9/2)² } + 9/2 // write 25–45 in place of -20

2+2 = { √ (5)² -2*5*9/2 + (9/2)² } +9/2 // expand in the form of (5-9/2)²

2+2 = { √ (5 - 9/2)² } + 9/2

2+2 = 5 - 9/2 + 9/2 // cancel 9/2

2+2 = 5

finally add 1 to both sides

so, 5=6

Answer 2

Answer:

2+2=4

2+2 = 4 + 9/2 - 9/2 //add and subtract 9/2

2+2 ={ √(4- 9/2)² } + 9/2 //square root and whole square

2+2 = { √ 16 - 36 + (9/2)² } + 9/2 // open the whole square in the root

2+2 = { √ -20 + (9/2)² } + 9/2

2+2 = { √ 25–45 + (9/2)² } + 9/2 // write 25–45 in place of -20

2+2 = { √ (5)² -2*5*9/2 + (9/2)² } +9/2 // expand in the form of (5-9/2)²

2+2 = { √ (5 - 9/2)² } + 9/2

2+2 = 5 - 9/2 + 9/2 // cancel 9/2

2+2 = 5

finally add 1 to both sides

so, 5=6
