Answer» a special product - a square of a binomial. So what you do first is to get the square root of the first term. You must get the square root of 9X2 which is 3x. Then, you get the square root of 25 which is 5. Put them TOGETHER but leave a space in the middle for the sign. Since the middle term is POSITIVE, we put a plus sign so the FINAL answer is (3x+5) WHOLE SQUAREDONT GET CONFUSED IN SQUAREHOPE IT HELPS YOU..\MARK AS BRAINLY/ |
