expanding bracket is basically multiplying and is used in algebra
for example:
2(6x+7x)
You multiply everything outstide the bracket with everything inside the bracket
for example:
2 x 6x=12x 2 x 7x= 14x
so now you have expanded the brackets it looks like:
12x + 14x
now simplify to make 26x . And that is how to expand brackets
( )( ) -> ( )( ) -> ( )( )
(a + 5) (a - 5) = a2 - 25
To expand an equation you multiply the number outside the bracket with everything inside the bracket. ex. 3(x+3) becomes 3x+9
To expand three brackets, expand and simplify two of the brackets then multiply the resulting expression by the third bracket. (FAIZAN BHAI GHAZI)CHANNEL
Expand the bracket.
x(x-1)(x-1)FOIL SIMPLIFY TIMES EVERYTHING IN THE BRACKETS BY X i will let you work it out
7(a + 3) = 7*a + 7*3 = 7a + 21
5(y+1)-2y5 x y = 5y5 x 1 = 55y + 5 - 2y5y - 2y = 3y3y + 5
Pipe bracket.
3(7a - 5b) + 2(4a - 3b) Multiply the contents of each bracket by the number outside it: 21a - 15b + 8a - 6b Bring like terms together: 21a + 8a - 15b - 6b Combine like terms: 29a - 21b This cannot be simplified further.
If a seized bottom bracket is encountered during a bicycle maintenance check, the following steps should be taken: Apply penetrating oil to the area and let it sit for some time to help loosen the rust or corrosion. Use a bottom bracket removal tool to try and unscrew the bottom bracket. If the bottom bracket is still stuck, apply heat using a heat gun to help expand the metal and break the bond. If all else fails, seek professional help from a bike mechanic to avoid causing further damage.
The compatible bottom bracket options for a UN55 bottom bracket are square taper bottom brackets.
