Complete the factorization. a2 + 3a – 28 = (a – 4)(a +
Hi Fweind
Whut u think it is :D
The 2 after the A is an exponent by the way.
a+6
Is that the answer?
Is the 6 after the a, or is a+6 after the a at the end?
What two numbers can you multiply together to make 28 and add up to 4?
Can you just show me how to factor?
Break 28 up into its prime factors and you should see it. I won't solve it for you because you need to know how to do it yourself. I'll help you.
28 factors into 2 * 14. What are the factors of 14?
What two numbers can you multiply together to make 14 besides 1 and 14?
2 and 7.
if u wanna factor the only thing u should do is to say: ____ + ____ = 3 ____ * _____ = -28 now u can say -4 and 7 lets check it : 7 - 4 = 3 7 * -4 = -28 :))) i hope this is helpful have a nice day
If you break the last term up into its prime factors you should be able to find a combination of those factors that when multiplied together equal the last term and when added together equal the middle term. 2 * 2 * 7 = 28 4 * 7 = 28 7-4=3
Is 3 the answer?
no the answer is 7
