How do you solve 2b2 plus 5b-35?
Assuming the equation is 2b2+5b-35=0, the quadratic formula is one way to solve this equation. It can't be factored easily. Do not confuse the "b" variable in the formula given with the "b" in the related link. The values of a, b, & c are as follows to be used in the quadratic formula: a=2, b=5, c= -35. Placing these values in the quadratic formula gives: (-5+/- sqrt(52-4*2*(-35)))/(2*2). This yields variable b = (-5+/- sqrt(305))/4 or (-5+17.46425)/4 & (-5-17.46425)/4 = 3.11606 & -5.61606 which are the two roots of the given equation.
What is the geometric mean for 3 and 12?
Per the formula in the related link, substitution into the formula yields (3*12)1/2, which is (36)1/2 or 6.
What is the square root of a polynomial?
The square root of a polynomial is another polynomial that, when multiplied by itself, yields the original polynomial. Not all polynomials have a square root that is also a polynomial; for example, the polynomial (x^2 + 1) does not have a polynomial square root in the real number system. However, some polynomials, like (x^2 - 4), have polynomial square roots, which in this case would be (x - 2) and (x + 2). Finding the square root of a polynomial can involve techniques such as factoring or using the quadratic formula for quadratic polynomials.
Derive the formula for radius if the formula is c equals pi times r squared?
Where pi (~ 3.1416) is represented by π, The formula C= πr2 yields the formula r2 = (C/π) therefore r = square root (C/π). ...which is the same as : r = (C/π)1/2.
What is the volume of a right circular cylinder with a radius of 6 and height of 10?
The formula is pi X radius2 X height. Application of this formula yields a value of about 1.130973355 X 103 of the cubic units corresponding to the length unit for the radius and height.

When dissolved in water an arrhenius base yields?
When dissolved in water, an Arrhenius base yields hydroxide ions (OH⁻) as the only negative ions in solution. This is because Arrhenius bases are substances that increase the concentration of hydroxide ions in aqueous solutions.
How can you tell when a quadratic equation has two identical rational solutions?
When b^2=4ac the zero is at a single point. The parabola does not penetrate the x axis. This represents two zeros, both with the same value. Example: x^2+4x+4 yields two zeros, each at x=-2. Notice that b^2=16=4ac. So Bob's your uncle!
