    you can't have a square of a negative number so 3x + 4 must be greater than or equal to zero so your domain is \[3x + 4 \ge 0\] \[x \ge -\frac{4}{3}\]

    okay so you need two numbers that multiply to 20 and add up to 9 the numbers at multiply to 20 are 2,10 1,20 and 4,5 only 4 and 5 add up to 9 so it's 4 and 5 so (x + 4)(x + 5)

    no, this one is different, because there's a 4 in front of the a squared.

    I'm going to try to explain this...so bear with me.... :x so your answer is going to be something like this with numbers in place of the _ (_a + _)(_a + -)
