What is the quadratic formula

Quadratic equation has form:

ax^2 + bx + c = 0

As the described discriminant:

=> a = 1, b= 3, c = 2

=> x^2 +3x + 2 = 0

=> Option D is correct.

Hope this helps!

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
