(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.
yes
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
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
you can't.
Yes it will, as long as you have the factory bracket still installed from the factory deck. If you have the bracket, it's basically a drop in installation.
Numerals in double brackets indicate multiplication by ten thousand. X = 10 but ((X)) = 100,000
