Factor the polynomial P(x)=x^3-2x^2-13x-10. Then solve the equation P(x)=0. This is what I got: P(x)=(x+1)(x^2-3x-10) P(x)=(x+1)(x-5)(x+2) When it says solve the equation P(x)=0 does it means solve for x? If so then x=-1 or 5 or -2 Correct??? please and thank you

A golfer hits a ball from the origin with an initial speed of 35 m/s at an angle of 44 degrees above the horizontal axis. The ball is moving down when it lands on a green that is 3.00 m above the level where it was struck. Neglect air resistance. 1. How long is the ball in the...

I posted this last night but it didn't get answered. So I'm posting it again with hopes that, this time, it will be answered. Please solve for x: |x-6|>7 I got x=6 as a final answer, but that doesn't make sense because 6 is not greater than 7. Please help!! Thanks :)

**Math help please**

1. Solve for x. 4(x - b) = x b = 4/3x b = 3/4x x = 4/3b x = 3/4b 2. Solve for y, then find the value of y when given x = 2. 6x = 7 - 4y -12 7/4 19/4 24 I need help solving these. Can you please explain how to solve these problems?

Use your knowledge of exponents to solve. a) 1/2^x=1/(x+2) b) 1/2^x>1/x^2 So I know that these functions are rational functions.. and I am trying to solve for x. I tried to solve them by I keep getting stuck with the exponent 2 which is the exponential function.. Help please

**Algebra--Correction?**

Solve 4(2x-3) < 3x+6 Would the solution be x > 18/5? * Algebra - Reiny, Tuesday, October 13, 2009 at 5:30pm yes again! Hold on... Looking back on this problem, wouldn't it be x < 18/5 since you need to flip the sign when you divide by a negative?

I just don't understand this question: h(t)=A*b^x h(3)=4 h(5)=40 Solve for b Would you plug 3 into the x and set it equal to 4? (4=A*b^3) How would you solve for that because in the next question they go on to ask you to solve for A using the b you found... Almost looks like ...
