-3/2

2 + tansquareA + cossquareA

y = 2x2 + 3 does not intersect the x-axis at all. It has two imaginary roots at ±i * square root of 3/2.

You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.

There are no real root. The complex roots are: [-5 +/- sqrt(-3)] / 2

-3/2

2 + tansquareA + cossquareA

3x^2=-20 so x^2=-20/3 this has no real roots but the plus of minus i(square root of 20/3) is a solution if we allow complex numbers.

It has roots x = 2.618 and x = 0.38197

It is a quadratic equation with no real roots or real solutions. In the complex domain, the solutions are 1 +/- i where i is the imaginary square root of -1.

2 and 3

y = 2x2 + 3 does not intersect the x-axis at all. It has two imaginary roots at ±i * square root of 3/2.

square root of 4x is 2 times square root of x, so answer is square root of x times 3 since it is 2 square roots of x plus one of them

You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.

15,000 to the third power that equals pi plus 12 would make it the square root of 7
