What is 4x2-13x-12 divided by 4x plus 3?
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
How do you factor this expression completely 3x2 4x-15?
(3x - 5)(x + 3)
What is the constant of this expression 5-4x plus x-3?
5-4x=x-35-4x+4x=x-3+4x (adding 4x on both side)5=5x-35+3=5x-3+3 (adding 3 on both side)8=5xx=8/5
Three more than the product of a number and 4 is 15 Find the number?
3+4x=15 4x=15-3 4x=12 x=12/4 x=3 The check is: If x=3 then, 3+ (4 X 3)=15 3+12=15

How do you factor 4x2 4x-15?
If that's - 4x, the answer is (2x + 3)(2x - 5) If that's + 4x, the answer is (2x - 3)(2x + 5)
What is 7x - 4x plus x - 15?
To do this equation, you collect like terms. 7x-4x+x-15 is your original equation, you have 3 terms with "'x'" in them, and they are 7x, -4x, and x. 7x + (-4x) +x simplifies to 4x, because 7-4 = 3 + 1 = 4 (the x is really 1x....). After this, you get 4x-15, which is as simplified as this equation can be.
