It cannot be factored because the discriminant is less than zero. Do you mean x2+11x-60 then if so it is (x-4)(x+15)
Yes that is correct
If 40 plus x equals 25 then x is equal to -15.
15
7+x=15 x=8
2x2 + 11x + 15 = (x + 3)(2x + 5).
If you mean: 2x2+11x+15 then it is (2x+5)(x+3) when factored
13x + 15 = 11x - 5 2x = -20 x = -10
If: 11x+25 = 7x+15 then there is only one solution and it is x = -2.5
x = -11
You have to experiment with different factors of 2, and different factors of 15. In this case, 2x2 - 11x + 15 = (2x - 5) (x - 3)
8x - 7 = 15 + 19xsubtract 19x from both sidesadd seven to both sides8x -19x = 15 +7-11x = 22divide both sides by -11x = -2
2x2+13x+15 = (2x+3)(x+5)
What is the solution set of 2x2 + x = 15
2(4)^2 - 1 = 4(4) + 15 31 = 31 yes!
12x+15p-6p+11x = 12x+11x+15p-6p = (12+11)x+(15-6)p = 23x + 9p
So you've got x=4 and y=3. 11x + 5y = 11(4) + 5(3) = 44 + 15 = 59
