It cannot be simplified any further, so it is: x² + 2x - 35
14x2 - 39x - 35 = (7x + 5)(2x - 7)
The answer is 35. 2x2-6x+15 2(-2)2-6(-2)+15 8+12+15 35. And this is not calculus...
X2 + 2X - 35 What two factors of - 35 add up to 2? (X - 5)(X + 7) -----------------
If you mean: 2x^2 -5x = 35 then 2x^2 -5x -35 = 0 and by using the quadratic equation formula the value of x is (5-square root 305)/4 or (5+square root 305)/4
It cannot be simplified any further, so it is: x² + 2x - 35
14x2 - 39x - 35 = (7x + 5)(2x - 7)
If: 9-2x = 35 Then: -2x = 35-9 => -2x = 26 So: x = -13
If 9-2x =35 -2x = 35-9 -2x = 26 -x = 13 x = -13
The answer is 35. 2x2-6x+15 2(-2)2-6(-2)+15 8+12+15 35. And this is not calculus...
X2 + 2X - 35 What two factors of - 35 add up to 2? (X - 5)(X + 7) -----------------
(2b - 5)(b + 7)
x2 - 2x + 55 = 90x2 - 2x - 35 = 0(x+5)(x-7) = 0x = -5, 7
2x + 5x = 35 7x = 35 x = 35/7 x = 5
35 squared is 35 x 35 or 35^2 or 1,225.
35 squared can be written as 352
y= 2x + 5y= -.2x 4multiply second equaoitn by 1010y= -2x-40then add the equaoitns11y= -35y= -35/11then plug that into either equaoitn and solve for x-35/11=-.2x-49/11= -.2x-45/11=xthere is only 1 solution since the equaoitns are linearly independent +1Was this answer helpful?
