Use the quadratic formula to solve the equation 9x^2 - 2=0

x = ±(√2)/3

Step-by-step explanation:

For the quadratic ...

ax^2 +bx +c = 0

the quadratic formula gives solutions as ...

x = (-b ±√(b^2-4ac))/(2a)

Comparing your quadratic to the general form above, we find ...

a = 9; b = 0, c = -2

Filling these values into the formula gives ...

x = (-0 ±√(0^2 -4(9)(-2)))/(2·9)

x = ±(√72)/18 = ±(6√2)/18

x = ±(√2)/3

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
