how to factor 2x 2 7x 3

SOLUTION: Factor if possible 2x^2+7x+3

Factor 2x^x+3 2x2 ? 7x + 3 2 x 2 - 7 x + 3 For a polynomial of the form ax2 +bx+ c a x 2 + b x + c, rewrite the middle term as a sum of two terms whose product is a?c = 2?3 = 6 a ? c = 2 ? 3 = 6 and whose sum is b = ?7 b = - 7.

I have the answer in front of me which is - 2x-1 x-3 but I have no clue how to arrive at it which is a little embarrassing. Can someone please give me steps too how to factor it?

Use FOIL to solve. The first thing done was to take a negative sign out of each term. This changes all additions to subtractions and all subtractions to additions. The two numbers multiplied together must be 3, and the only two numbers that work are 1 and 3. A bit of trial and error will give the answer. Trending News.

Step by step solution :

Apr 10,  · Explanation: using the a-c method of factorising. the factors of 2 ? 3 = 6. which sum to + 7 are + 6 and + 1. split the middle term using these factors. ? 2x2 +6x + x + 3 < factor by grouping. = 2x(x + 3)+1(x + 3) take out the common factor (x + 3). You can put this solution on YOUR website! 2x + 7x + 3 2 x + 7 x + 3 1. Multiply the blue 2 by the red 3, getting 6. 2. Think of two positive integers which have product 6 and which have SUM (since the purple sign is +) equal to the green 7. Such positive integers are 1 and 6 because 1 6 = 6 and 1+6 = 7 3. 2x? + 7x + 3 (3*2 = 6 and factors of 6 are: 1,2,3,6,. So we take 6 and 1) = 2x? + (6x + x) + 3 =2x? + 6x + x + 3 =2x (x+3) + 1 (x+3) = (2x+1) (x+3) So, 2x + 1 = 0. x = -? And, x + 3 = 0 x = - 3.
