What is 5x-8 plus 7x simplified to?
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
2x2 plus 7x - 15 equals 0?
2x2 + 7x - 15 = 02x2 + 10x - 3x - 15 = 0(2x2 - 3x) + (10x - 15) = 0x(2x - 3) + 5(2x - 3) = 0(2x - 3)(x + 5) = 0(2x - 3) = 0 or (x + 5) = 0x = 3/2 or x = -5
Factor the trinomial and enter your answer below Write each factor as a polynomial in descending order14x2 plus 29x - 15?
14x2 + 29x - 15= 14x2 + 35x - 6x - 15= 7x(2x + 5) - 3(2x + 5)= (2x + 5)(7x - 3)
What is the answer to 7x 7x squared?
7x^3. That is 7x cubed.... or 7x*7x*7x (where * means multiply). You should get 343x

what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
What is 5x-8 plus 7x simplified to?
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
How do you solve 5x-3 equals 11 plus 12x the solution is x equals?
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
How do you factor 12x squared -7x -12?
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored
6x² plus 7x equals 5?
6x2 + 7x = 56x2 + 7x - 5 = 0x =[ -7 ± √[72 - 4(6)(-5)] ]/2(6)x = [-7 ± √(49 + 120)]/12x = (-7 ± √ 169)/12x = (-7 ± 13)/12x = (-7 + 13)/12 or x = (-7 - 13)/12x = 6/12 = 1/2 orx = -20/12 = - 5/3
Factor as a polynomial in descending order14x2 plus 29x - 15?
(7x-3)(2x+5) 14x2 + 29x - 15, write 29x = 35x - 6x = 14x2 - 6x + 35x - 15 = (14x2 - 6x) + (35x - 15) = 2x(7x - 3) + 5(7x - 3) = (7x-3)(2x+5)
