x2+12x+36=0 2x+12x+36=0 14x+36=0 14x=-36 x=-36/14 x=-2 4/7

3x2+14x+8 = 0 x = -2/3 or x = -4

The roots are: x = -5 and x = -9

x^2 + 14x + 40 factorises as (x + 10)(x + 4) so the roots are x = -10, -4.

y=-2/3x with any y-intercept except -2.

That is a quadratic equation. You can solve it easily if you factor it to 2(2x - 1)(3x - 2) and find what makes each factor 0. The solutions are 1/2 and 2/3; you can see the steps taken to get here using the link under "related links".

x2 + 14x + 45 = 0 => x2 + 9x + 5x + 45 = 0 => x(x + 9) + 5(x + 9) = 0 (x + 9)(x + 5) = 0 so that x = -5 or x = -9

The answer is [ x = 1/7 ].

x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7

(4x + 5)(3x - 7)

Please do not remove this question from Inappropriate or split any alts from it. Thanks!

x2-14x+45=0(x-9)(x-5)=0x-9=0 & x-5=0x=9 & x=5

Re-arranging, x2 - 14x +49 = 0 Factorising, (x-2)(x-2) = 0, hence x=2.

12x2 + 8x = 0 4x(3x + 2) = 0 Two solutions: 1. x = 0 2. x = -2/3

2(4x^2 - 7x + 5)

"sum" is not the right word here. All the bits are not being added: there is an equals sign. But 9x plus 14x can only be 23x, so that 23x + 8 = 0. Take 8 from each side of the equality so 23x = -8, and then divide both sides by 23 to get x = -8/23 Don't confuse"x" with the multiplication sign. For that reason, in algebra, a curly x is used wherever possible.

Yes because if 1+0=1 than 0 plus b equals b

x = 1.5 because -7x + 3 = -15/2 -14x + 6 = -15 (x2) -14x + 21 = 0 (+15) 21 = 14x (+14x) 3 = 2x (/7) 1.5 = x

I would think -5 plus 5 equals 0.

Without an equality sign the given expression can't be considered to be an equation but if it equals 0 then using the quadratic equation formula will give its solutions.

15 = 8x2 - 14x; whence, 8x2 - 14x - 15 = (2x - 5)(4x + 3) = 0. Therefore, x = 5/2 or -3/4.

It equals 7

x = y = 0 ?
