Factor 3x^2 + 13x + 4?
explain the steps!
^ = to the power of

Since coefficient of x^2 is prime and both second and third term are positive, it must be in form (3x+_)(x+_).

There is three possibles for these blank spaces;
1,4
2,2
4,1

Because coefficient of second term is 13 = 1+12 = 1+3*4, these blank space should be 1,4

So your answer is (3x+1)(x+4)

Hope this makes sense.

Sinx = c/b

cosx = a/b

tanx = c/a

Step-by-step explanation:

B is hypotenuse, a is adjacent, c is opposite of angle x.

Sin = opposite/hypotenuse

cos = adjacent/hypotenuse

tan = opposite/adjacent
