    • @gabbytimpug8399
      @gabbytimpug8399 Рік тому +4

      Yes, he used multiplication because 3² or 3 squared is 3 x 3, which is equal to 9.
      Another ex is 5², which is 5 x 5
      3³ or 3 cubed is equal to 3 x 3 x 3.

    thank you sir for helping us find the quadratic equation by completing square!
    I just have one question. in 1:35. you mentioned that transpose"-2" to the other side. how is it still 2 when we transpose it? because the meaning of transpose is just changing position. but It changed the value.
    thank you for answering!

    • @mangsom2256
      @mangsom2256 7 місяців тому +1

      It is because you transposed the -2 to the other side of the equal(=) sign. Therefore, the negative(-) sign will be changed to a positive sign. I'm not that good at explaining, but I hope this helps :)

    • @joesmart9483
      @joesmart9483 4 місяці тому

      Maybe an easier way to express this is to add 2 to both sides of the equation. The +2 and the -2 become zero, or cancel out, or however you visualize it, and you have +2 on the other side.

    • @Prama.23
      @Prama.23 Рік тому +1

      1. find the square root of the first term (x) since the first term doesn't have a numerical coefficient then just copy the variable (x__)
      2. copy the sign of the middle term , since the middle term is positive then the sign will be positive (x+_)
      3. Find the square root of the last term , since the last term is 9 you can extract it
      and it becomes 3 (x+3) then you can finally square the equation
      (x+3)²

    • @thomassidoti5496
      @thomassidoti5496 2 місяці тому

      x^2+6x+9 factors out to (x+3)(x+3) which can be expressed as (x+3)^2 since we are multiplying x+3 by itself

    if x = root(11) -3 or -root(11)-3, then putting those in x^2+6x+9 doesn't work out. You end up with (root(11) -3)^2 + 6(root(11)-3) -2 = 0. That doesn't work out.
