(2x^2 + 10x + 12) divided by (x + 3) your question is (2x^2 + 10x + 12)/(x + 3) =2(x+2)(x+3)/(x+3) = can you take it from here?

math
evaluate this exprssion 3X^3+5x10X^210X

Math
4/10x 9 < 9/10 = x < 24 3/4 Did I do this right? was solving for the inequality and the 4/10x is together.

Math(Please check my work.)
(2x3)(x^2+5x3)=2x+10x^215x+9 *Is this correct.? this is a different problem... Here's how this one works out: ......x^2 + 5x  3 ............2x  3 ================== ...... 3x^2  15x + 9 2x^3 + 10x^2  6x ====================== 2x^3 + 7x^2  21x + 9

Math
I solved the equation below and got an answer of 9+sqrt(57) but i don;t belive this is correct. help please. 5sqrt(8x+1)=x 8x+1=x^210x+25 0=x^210x+258x1 0=x^218x+24 then i completed the sqare got 9+sqrt(57) THANKS SO MUCH
