Solve 922902064d^23-40

Question

Simplify the expression

2768706192 d^{2} - 40

Show Solution

8 (346088274 d^{2} - 5)

Show Solution

d_{1} = - \frac{35315130}{49441182}, d_{2} = \frac{35315130}{49441182}

Alternative Form

d_{1} \approx - 0.00012, d_{2} \approx 0.00012

Evaluate

922902064 d^{2} \times 3 - 40

To find the roots of the expression,set the expression equal to 0

922902064 d^{2} \times 3 - 40 = 0

Multiply the terms

2768706192 d^{2} - 40 = 0

Move the constant to the right-hand side and change its sign

2768706192 d^{2} = 0 + 40

Removing 0 doesn't change the value,so remove it from the expression

2768706192 d^{2} = 40

Divide both sides

\frac{2768706192 d ^{2}}{2768706192} = \frac{40}{2768706192}

Divide the numbers

d^{2} = \frac{40}{2768706192}

Cancel out the common factor 8

d^{2} = \frac{5}{346088274}

Take the root of both sides of the equation and remember to use both positive and negative roots

d = \pm \frac{5}{346088274}
