6x2 = -7x -2
6x2 + 7x + 2 = 0
6x2 + 3x + 4x + 2 = 0
3x(2x + 1) + 2(2x + 1) = 0
(2x + 1)(3x + 2) = 0
2x + 1 = 0 or 3x + 2 = 0
So, x = -1/2 or -2/3
5.
technically it's already solved, you just have to graph it i guess.
You don't. There's no question there, and nothing that needs solving. If it were equal to something, then we could find what number 'x' must be.
If x squared equals n, then x is the square root of n.
2x2-5 = 0 +5 +5 2x2 = 5 /2 /2 x2 = 5/2 sqrt(x2) = sqrt (5/2) x = sqrt(5/2) Ps: Sqrt means square root
Solve this problem -x squared -40x- 80 =0
Solve using the quadratic formula
X=1
If x squared -10 = 0 then x = the square root of 10
First you must square the 6 which the answer is 36. Then you subtract 36 from 8 and the answer is negative 28. Finally you solve negative 28 minus 28 (-28-28) which equals negative 56 (-56).
You have to put your heart into it!

hello
x = 25 / 3squared + 5
Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
