What is the value of the discriminant polynomial 3x2 plus 6x plus 5?
b^2 - 4ac Is the discriminant. 6^2 - 4(3)(5) 36 - 60 = - 24 < 0 so, an unreal answer and no real X intercepts
What is the discriminant of 4x2 6x-5?

What value for x makes the following equation TRUE 6x 5 equals 31?
That depends on what you mean by "6x 5", which could be 6x * 5, 6x + 5, 6x - 5, 6x / 5, 6x5, etc.
-4x2 plus 6x plus 40 equals 0?
-4x2 + 6x + 40 = 0 ∴ -2x2 + 3x + 20 = 0 ∴ -2x2 - 8x + 5x + 20 = 0 ∴ -2x(x + 4) + 5(x + 4) = 0 ∴ (5 - 2x)(x + 4) = 0 ∴ x ∈ {5/2, -4}
What is -6x-5 plus -10?
-6x - 5 + 10It's an algebraic expression in 'x'. It can be simplifiedby combining like terms:-6x + 5Its numerical value depends on the value of 'x'.
