Question

I need help on some math problems plz!so stressed
3x^2+13x+9=0 <--- factor

4i(1+i)+4 / 2i

2x^2 + 7z less than or greater to 4...put this one on a number line

Answer 1

Plz help I dont get it and Can you show me the work so I can understand it

Answer 2

can you check the 1st question is correct...

otherwise it won't factor... and will need the general quadratic formula to solve it

Answer 3

x=-3x^2-12x-9

Answer 4

would that help?

Answer 5

well hopefully its

y = -3x^2 - 12x - 9

take out -3 as a common factor

y = -3(x^2 + 4x + 3)

factor the quadratic and its

y = -3(x + 3)(x +1)

hope it helps

Answer 6

thanks..can you help on the other 2 also?
