To find the solutions to an equation of the form ax2+bx+c , use the quadratic equation: x=−b±b2−4ac√2a . What are the two soluti

lidiya [134]

Answer:

1.686

Step-by-step explanation:

Given is an quadratic equation as

$2x^2-x-4=0$

Also we are given the formula for general equation

$ax^2+bx+c$ as

$\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

Here in our equation we have

$a=2\\b=-1\\c=-4$

Hence solution would be

$\frac{1+\sqrt{1+32} }{4} ,\frac{1-\sqrt{1+32} }{4} \\\frac{1+\sqrt{33} }{4} ,\frac{1-\sqrt{33} }{4}$

Greater would be the one with positive square root

$\frac{1+\sqrt{33} }{4} \\=1.6861\\=1.686$

V =x × y × z solve for x

kogti [31]

Hello from MrBillDoesMath!

Answer:

x = V/(y*z)

Discussion:

V = x * y* z => (divide both sides by y*z)

V/(y*z) = (x*y*z) / (y*z) =>

V/(y*z) = (y*z) * x / (y*z) => ( as (y*z)/(y*z) = 1)

V/(y*z) = 1 * x =>

V/(y*z) = x

Thank you,

MrB
