Write an equation in which the quadratic expression 2x^2-2x-13 equals 0

torisob [31]

Answer:

x = 3 and -2 are the two solutions.

Step-by-step explanation:

2x^2 -2x -12 = 0

First factor out a 2

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0

2 = 0 x - 3 = 0 x + 2 = 0

2 does not equal zero so this is an extraneous solution

x - 3 = 0 so x = 3

x + 2 = 0 so x = -2

tatuchka [14]

Answer:

second marble is blue and first marble is white is $\frac{1}{7}$

Step-by-step explanation:

given data

two marbles

box = 1 blue, 3 white, 2 green, and 2 red marbles

solution

we get here second marble is blue and given that the first marble is white

= P(3c1 × 1c1) ÷ P(3c1 × 7c1) ................................................1

= 1c1 ÷ 7c1

= 1 ÷ 7

so second marble is blue and first marble is white is $\frac{1}{7}$
