x2 + 10 x + 25 = 2 (x+5)2 = 2 x+5 = +/- sqrt(2) x = -5 +/- sqrt(2)
Just realize that multiplication is repeated addition. So you have 6 twos and 5 fives. that is 12+25 and now add 55 The total is 92
5 + 20 = 25
You take 4 times 5 which is 20 then 3 plus 2 which is 5. Add 20 plus 5 and you get 25. That's the answer.
If you mean 2(x+5) + (3*5) then it can be simplified to: 2x+25

6 + 5 + 3 + 2 + 9 = 25
x2 + 10 x + 25 = 2 (x+5)2 = 2 x+5 = +/- sqrt(2) x = -5 +/- sqrt(2)
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.

5 + 20 = 25
You take 4 times 5 which is 20 then 3 plus 2 which is 5. Add 20 plus 5 and you get 25. That's the answer.
If you mean 2(x+5) + (3*5) then it can be simplified to: 2x+25
