Solve for x...............
fomenos

Answer:

Option A

x=\frac{2(+/-)\sqrt{10}} {2}

Step-by-step explanation:

we have

2x^{2}-4x-3=0

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

2x^{2}-4x-3=0

so

a=2\\b=-4\\c=-3

substitute

x=\frac{4(+/-)\sqrt{-4^{2}-4(2)(-3)}} {2(2)}

x=\frac{4(+/-)\sqrt{40}} {4}

x=\frac{4(+/-)2\sqrt{10}} {4}

x=\frac{2(+/-)\sqrt{10}} {2}

Evaluate the polynomial f(x) =2x^3-4x^2+2x-8. At x=-2
Gelneren [198K]

Answer:

f(- 2) = - 44

Step-by-step explanation:

Substitute x = - 2 into f(x) and evaluate, that is

f(- 2) = 2(- 2)³ - 4(- 2)² + 2(- 2) - 8

        = 2(- 8) - 4(4) - 4 - 8

        = - 16 - 16 - 4 - 8

        = - 44

2min 30s = 2 1/2 min = 5/2 min; 10/(5/2) = 4 laps
