Answer:

x = ± \frac{2}{3}

Step-by-step explanation:

9x² - 4 = 0 ( add 4 to both sides )

9x² = 4 ( divide both sides by 9 )

x² = \frac{4}{9} ( take the square root of both sides )

x = ± \sqrt{\frac{4}{9} } = ± \frac{\sqrt{4} }{\sqrt{9} } = ± \frac{2}{3}

Where did Jordan make her mistake? GIVING BRAINLIEST!
Ivenika [448]

Answer:

Jordan made mistake in his first step while multiplying.

Step-by-step explanation:

Given expression of Jordan's work is

14(8+4x) = 6x-(5-11x)

In the first step, Jordan multiplied the numbers to remove the braces.

He multiplied 14(8+4x) wrong as 14*8 is 112 rather than 126and on the right hand side, he did not change the sign of 11x to positive as two negatives are positive when multiplied.

Hence,

Jordan made mistake in his first step while multiplying.
