Assuming you are trying to solve "(x - 1)(x + 2)(x - 3) = 0", when any number is multiplied by zero, the result is always zero, regardless of the other number(s). Thus each term in parentheses can be made zero in turn to find the solutions:
x - 1 = 0 → x = 1, giving (1 -1)(1 + 2)(1 - 3) = 0 × 3 × -2 = 0
etc.
Set all numbers and variables equal to zero. (2x3)-(3x2)-(20x)-21=0 Next, follow the order of p.e.m.d.a.s. 6-6-20x-21=0 -20x-21=0 Separate the numbers and variables -20x=21 x= -21/20
2 x 3 = 65 x -5 = -256 + -25 = -19
Since there is nothing following, none of them!
If you cannot do it using mental maths then resort to the calculator that comes with your computer.
Parentheses are the following symbols: ( & ). These are parentheses. These help to do equations for example : 3+2x3=9 u are to put the parentheses or the backetts or the {} to help solve the equation so this is the way to put them in : 3+(2x3)=9. Hope This Helps!
2x3-10 is -4, as (using BIDMAS), we firstly multiply 2 by 3 (6) and finally subtract the 10, leaving us with -4.
x2 • (5x2 + x + 8)

The commutative property of multiplication states that changing the order of numbers does not change the result or it's value. For example: If 3+2=5 Then 2+3=5 In multiplication: If 3x2=6 Then 2x3=6 There for 3x2=2x3
Please help me solve this 2x + 3 = 9 x =. x=3 because 2x3=6+3=9
It teaches you how to take jump in mind i.e if u have to solve 2+2+ 2=6, you just do 2x3= 6!!!! isn't it kool.
2X3 2 + 2 + 2 = 6 3 + 3 = 6 ^ thats how ^
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
