Solve 10x^2 9k=1 - ScanMath

Evaluate

10 x^{2} \times 9 k = 1

Multiply the terms

90 x^{2} k = 1

Rewrite the expression

90 k x^{2} = 1

Divide both sides

\frac{90 k x ^{2}}{90 k} = \frac{1}{90 k}

Divide the numbers

x^{2} = \frac{1}{90 k}

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

x = \pm \frac{1}{90 k}

Simplify the expression

More Steps

x = \pm \frac{10 k}{30 ∣ k ∣}

Separate the equation into 2 possible cases

x = \frac{10 k}{30 ∣ k ∣} x = - \frac{10 k}{30 ∣ k ∣}

Calculate

{k \neq = 0 x = - \frac{10 k}{30 ∣ k ∣} {k \neq = 0 x = \frac{10 k}{30 ∣ k ∣}

Solution

k \neq = 0, x = - \frac{10 k}{30 ∣ k ∣} k \neq = 0, x = \frac{10 k}{30 ∣ k ∣}
