14x2 - 39x - 35 = (7x + 5)(2x - 7)
X2 + 2X - 35 What two factors of - 35 add up to 2? (X - 5)(X + 7) -----------------
The answer is 35. 2x2-6x+15 2(-2)2-6(-2)+15 8+12+15 35. And this is not calculus...
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
2x+3x=35 5x=35 x=7

(2b - 5)(b + 7)
If: 9-2x = 35 Then: -2x = 35-9 => -2x = 26 So: x = -13
x2 - 2x + 55 = 90x2 - 2x - 35 = 0(x+5)(x-7) = 0x = -5, 7
2x + 5x = 35 7x = 35 x = 35/7 x = 5
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
If 9-2x =35 -2x = 35-9 -2x = 26 -x = 13 x = -13
2x+3x=35 5x=35 x=7
If that were + 35, it would factor to (x + 5)(x + 7) As it is, it doesn't factor neatly. Applying the quadratic formula, we find two real solutions: -6 plus or minus the square root of 71 x = 2.426149773176359 x = -14.426149773176359
2x + 5x = 357x = 35x = (35 / 7) = 5
