Question

Find the discriminate of the quadratic equation 4root2x2 +8x +2root2 =0

Answer 1

${4}^{2 \times 2 } + 8x + {2}^{2} = 0$
${4}^{4} + 8x + 4 = 0$
$256 + 8x + 4 = 0$

260+8x=0
$8x = - 260 + 0$
$8x = - 260$
$x = \frac{ - 260}{8}$

Answer 2

Answer:

D=0

Step-by-step explanation:

Given

4√2 x² + 8x +2√2 = 0

To determine the Discriminant of the quadratic equation,

Formula of the Discriminant = b²- 4ac

where, b = coefficient of x = 8

c= constant = 2√2

a= 4√2

a = coefficient of x²

Put the value on the formula,

D = (8)² - 4*4√2*2√2

D = 64- 64 = 0

If D=0, the equation has two equal root.
