To solve the equation (3x^2 + 4x + 5 = 0), we can use the quadratic formula (x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}), where (a = 3), (b = 4), and (c = 5). The discriminant (b^2 - 4ac) calculates to (4^2 - 4(3)(5) = 16 - 60 = -44), which is negative. This means there are no real solutions; instead, the solutions are complex: (x = \frac{-4 \pm \sqrt{-44}}{6} = \frac{-4 \pm 2i\sqrt{11}}{6} = \frac{-2 \pm i\sqrt{11}}{3}).
If you mean: 3x+2y = 6 and -4x+5y = 15 then it works out as x = 0 and y = 3
If you mean points of (0, 0) and (3, 4) then the equation works out as 3y = 4x or as y = 4/3x
They are x = -1 and x = 4.
To solve for ( x ) in the equation (-4x + 3(x - 7) - 12 = 0), first distribute the 3: (-4x + 3x - 21 - 12 = 0). Combine like terms: (-4x + 3x - 21 - 12 = -x - 33 = 0). Solving for ( x ), we get ( -x = 33), thus ( x = -33 ).
This is a quadratic equation requiring the values of x to be found. Rearrange the equation in the form of: -3x2-4x+6 = 0 Use the quadratic equation formula to factorise the equation: (-3x+2.69041576)(x+2.23013857) Therefore the values of x are 0.8968052533 or - 2.230138587 An even more accurate answer can be found by using surds instead of decimals.
It has no solution and if you mean 4x+10+3x+40-3x then it can be simplified to: 50+4x _________________________________________________________________________________________ Assuming that the equation is 4x+10+3x+40-3x = 0, then it will reduces to 4x = - 50, then the answer is: x = -12.5
Presumably this is an equation in the form of: 3x-4x+3 = 0 -x = -3 Therefore: x = 3
If you mean: 3x+2y = 6 and -4x+5y = 15 then it works out as x = 0 and y = 3
Assuming you mean:(4x+36)(8x-40) = 0 then you can use the property that a product can only be zero if one of its factors is zero. In other words, you can change this to: 4x + 36 = 0 OR 8x - 40 = 0 Solve each of the individual solutions; their solutions are also solutions to the original equation.
If you mean points of (0, 0) and (3, 4) then the equation works out as 3y = 4x or as y = 4/3x
Use the quadratic equation formula to find the solutions to this equation.
the equation has exactly 1 real solution. 8-4x=0 -> add 4x to both sides. 8=4 -> divide both sides by 4. 2=x.
They are x = -1 and x = 4.
How many solutions are there to the equation below? 3x-10(x+2) = 13-7x 0
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9
To solve for ( x ) in the equation (-4x + 3(x - 7) - 12 = 0), first distribute the 3: (-4x + 3x - 21 - 12 = 0). Combine like terms: (-4x + 3x - 21 - 12 = -x - 33 = 0). Solving for ( x ), we get ( -x = 33), thus ( x = -33 ).
