How do you factor this 2x2 plus 13x plus 15?
2x2+13x+15 = (2x+3)(x+5)
7x-5 plus 2x equals 3-4x plus 12?
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
How do you factor 2x to the second power plus 13x plus 15?
2x^2 + 13x + 15 factored means that the two numbers must multiply to the constant (15) and add to equal the coefficient on the X (13). So it becomes: (2x + 3) (x + 5). If expanded, 2x*5 = 10x and 3 * x = 3x which add to 13x. And 5 * 3 = 15
What is the order pair 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2 ..... Eq.1-3x - y = -3 ..... Eq.2 .... we can write it in another form y = 3 - 3xPut the value of y in Eq.1 the result will be :2x + 5(3 - 3x) = 22x + 15 - 15x = 22x - 15x + 15 = 2-13x + 15 = 2-13x = 2 - 15-13x = -13x = -13/-13 ......... X = 1to find Y, put the value of X in Eq.2y = 3 - 3xy = 3 - 3(1)y = 3 - 3 .......... Y = Zero
What 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 equals to?
It equals 285

Solve the system of equation using substitution 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero
How do you factor 2x2 plus 13x plus 15?
2x 2+13x+15 = (2x + )(x + ) since the only way to get 2 is 1 times 2. The missing numbers must be filled with with 1 and 15 or 3 and 5 in some order, so by trial and error we get. 2x 2+13x+15 = (2x + 3 )(x + 5 )

Factor this polynomial completely -4x4 plus 26x3-30?
-2(2x^4 - 13x^3 + 15)
13 x equals 15-2x?
13x = 15 - 2 x Solve for x 1. Get the x's on one side. Add 2x to each side. 13x + 2x = 15 - 2x + 2x This is the same as 15x = 15 2. Get x by itself. Divide each side by 15. 15x/15 = 15/15 x = 1
15 plus what equals -30?
-15
How do you factor 6x2-13x plus 15?
It cannot be factored because the discriminant of b2-4ac is less than zero.
