You would do 150/15=10 since this is a percent change it to a decimal(.10) to check do 150x.10=15 and 15/.10=150

What are all the roots of the equation x^2+6x-9
frez [133]

Answer:

x = - 3 ± 3\sqrt{2}

Step-by-step explanation:

given the equation x² + 6x - 9 = 0

We can solve for x using the quadratic formula

x = ( - b ± \sqrt{b^2-4ac } ) / 2a

with a = 1, b = 6 and c = - 9

x = ( - 6 ± \sqrt{6^2-(4(1)(-9)} ) / 2

  = ( - 6 ± \sqrt{36+36} ) / 2

  = ( - 6 ± \sqrt{72} ) / 2

  = ( - 6 ± 6\sqrt{2} ) / 2

x = - 3 ± 3\sqrt{2}
