Without an equality sign it can't be considered to be an equation
9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
Expression. Equations have equals signs.
-6x^2 - 78x - 252 Improved answer: -6x+6x+7 When simplified = 7
Yes.

Yes, y = 4x + 7 is a linear equation.
9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
Expression. Equations have equals signs.
Y = X2 + 6X + 2set to 0X2 + 6X + 2 = 0X2 + 6X = - 2now, halve the linear coefficient ( 6 ), square it and add it to both sidesX2 + 6X + 9 = - 2 + 9gather terms on the right and factor the left(X + 3)2 = 7(X + 3)2 - 7 = 0==============vertex form(- 3, - 7)=======vertex
A quadratic equation. If you wish to solve for x, you can do so as follows: -x2 + 6x + 7 = 0 x2 - 6x - 7 = 0 (x - 7)(x + 1) = 0 x ∈ {-1, 7}
-6x^2 - 78x - 252 Improved answer: -6x+6x+7 When simplified = 7
No, it is not.
7+10+(-6x)=17-6x
Yes.
