7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2

3

(2a - 5). Take the value of a. Double it to get 2a Take away (subtract 5) to get 2a - 5

(a + 5) (a - 5) = a2 - 25

(x-2)*(2x2+5x-3) Multiply out the brackets term by term taking care with the minus terms:- 2x3-4x2+5x2-10x-3x+6 Collect like terms:- Answer: 2x3+x2-13x+6

Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether "x plus y squared" means x + y^2 or (x + y)^2. You will need to use a code, for example b1 (open bracket) and b2 (close bracket), because the browser will reject brackets!Here, it is not clear whether you mean 2^a + 3 or 2^(a+3)

Set up two brackets. Since 7 only has two factors, put 7x in one bracket and x in the other. The two other numbers will be a factor pair of 16 (16,1)(8,2)(4,4). Since the signs are minus, one of the brackets will be plus and one will be minus. Now you just have to put it together in a way that fits. We used to call that trial and error, now it's called guess and check. (7x + 4)(x - 4)

Expanding brackets in math is simply multiplying all expressions inside the bracket with the variable or coefficient outside. For example: 3x(5 + 3y) = 2 To expand the brackets, simply multiply 3x with each of the expressions inside, always keeping in mind the sign of the answer (negative/positive) Step 1: (3x * 5) + (3x * 3y) = 2 Step 2: 15x + 9xy = 2 Here is another example in which the signs change from negative to positive: -3 (-2x + 4) = 1 Since you multiply -3 with -2x, you are multiplying a negative value with a negative value. Minus ( - ) and minus (-) multiply to give a positive value. Step 1: (-3x * -2x) + (-3x * 4) = 1 Step 2: 6x - 12x = 1 You will notice that, in time, as you continue to practice with these types of questions, you will not be needing Step 1 and be able to skip to Step 2. Another example, in the case where you have brackets^squared 3(2x + 5)^2 = 4 In this case, you cannot directly multiply 3 with the expressions in the bracket since they are being squared and must be evaluated first. In the case where you have a polynomial which is being squared, you must expand it first using the rule: Note: ^2 means squared (Just like 5^2 = 25) (a + b)^2 = a^2 + 2ab + b^2 [Where a and b may be any value which cannot be solved directly using arithmetic] So in the case above you use this rule. 2x is 'a' and '5' is b. 3(2x + 5)^2 = 4 3(4x^2 + 2(2x)(5) + (5)^2) = 4 3(4x^2 + 20x + 25) = 4 At this point, you may multiply the brackets, since the term inside has been fully expanded. (3 * 4x^2) + (3 * 20x) + (3 * 25) = 4 12x^2 + 60x + 75 = 4 You have successfully expanded the brackets at this point =D. In the case where you have two brackets: (a + b)(b + c) = 3 You must multiply each term in bracket #2 with each term in bracket #1. Start with multiplying a with b and c, then b with b and c. (a*b) + (a*c) + (b*b) + (b*c) = 3 ab + ab + bb + bc = 3 Hope this helps...
