Question:

how do you expand these brackets with numbers on the outside?

hi i want to expand these brackets because i have yet to work out how to do it and i have got an exam on Monday. so these are the brackets 3(2x + 3) + 2(x + 1) please could you do this through the grid methods as i find this the most easiest to follow. There will be an immediate 10 points given for good and simple answer thank you

Answer:

Basically, what it means is that you do 3x what ever is in the brackets for the first one and 2x whatever is in the second bracket; 3x2X6X 3x39 so for that bracket the answer is 6X+9 do the same for the second one: 2xX2X and 2x12 so putting that into simpler terms; 6X+2X+9+2 so the answer is 8X+11 bbc .uk/schools/ks3bitesize/maths/algebra/formulae2/revise4.shtml Will help as the method I used wasn't the grid method but scroll down on there and there is an example with the grid method. Good luck
Multiply the number outside the bracket but each thing inside the bracket. 3(2x + 3) + 2(x + 1) (3*2x + 3*3) + (2*x + 2*1) 6x + 9 + 2x + 2 8x + 11
The others have nicely and actually lined the FOIL technique, and the occasion you have given is a classic difference between 2 squares factorization. I in basic terms pick to show that, interior the main commonly used words (a + b)(x + y) a(x + y) + b(x + y) after which you comprehend what to do. because of the fact the problem that a is multiplying is an identical because of the fact the problem that b is multiplying, you are able to group a and b jointly as shown. –––––––––––––––––––––––––
