I am going to assume that your question is telling us that this expression is equal to 0. If we do not know what it is equal to then we can not answer the question.
2x2 + 7x + 6 = 0
This factors easily to:
(x + 2) (2x + 3) = 0
Thus
x + 2 = 0
x = -2
and
2x + 3 = 0
x = -3/2
x = -1.5

What is the value of the discriminant for the equation 2x2 plus 3x-4 equals 0?
2X2 + 3X - 4 = 0the discriminant is,b2 - 4ac32 - 4(2)(- 4)9 + 32 = 4141 > 1this means there are two real roots to this equation
How many times does the graph of y equals 2x square plus 3 intersect the x-axis?
y = 2x2 + 3 does not intersect the x-axis at all. It has two imaginary roots at ±i * square root of 3/2.
How many roots does 3x2 plus 4x plus 3 have?
two complex
2x2 plus 42 equals x2 plus 13x?
This is a quadratic equation question which will have two answers: 2x2+42 = x2+13x 2x2-x2-13x+42 = 0 x2-13x+42 = 0 Factorising the equation gives you: (x-6)(x-7) = 0 Therefore: x = 6 or x = 7
How many real roots exist if the discriminant of the equation plus 0?
If the discriminant of a quadratic equal is zero then it will have two equal roots.

Which two values of x are roots of the polynomial below x2 plus 5x plus 11?
There are none because the discriminant of the given quadratic expression is less than zero.
Which two values of x are roots of the polynomial below x2 plus 5x plus 9?
x = -2.5 + 1.6583123951777ix = -2.5 - 1.6583123951777iwhere i is the square root of negative one.
X2-11x plus 13 has two values of x are roots of a polynomial what is it?
x=11+69/2 and x=11-69/2
Which two values of x are roots of the polynomial x2 plus 3x - 5?
x2 + 3x - 5 is an expression, not an equation. An equation may have roots, an expression does not. However, x2 + 3x - 5 = 0 is an equation and its roots are -4.1926 and 1.1926 (approx).
How many times does the graph of y equals 2x square plus 3 intersect the x-axis?
y = 2x2 + 3 does not intersect the x-axis at all. It has two imaginary roots at ±i * square root of 3/2.
How many roots does 3x2 plus 8x plus 3 have?
two negative
How many roots does 3x2 plus 4x plus 3 have?
two complex
How many real roots does the equation 2x2-5x-3 equals 0 have?
2x2 - 5x - 3 = 0 A quadratic equation expressed in the form ax2 + bx + c = 0 has two real and distinct roots when b2 - 4ac is positive. Using the figures from the supplied equation then b2 - 4ac = 52 - (4 x 2 x -3) = 25 + 24 = 49. Therefore there are TWO real and distinct roots.
How many complex roots does 6x4 plus x3 - 5 equals 0 have?
It has two complex roots.
2x2 equals 4 what is two?
If: 2x2 = 4 Then: x = the square root of 2
