Answer:
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate to zero
so
substitute in the formula
therefore
StartFraction 7 minus StartRoot 65 EndRoot Over 2 EndFraction comma StartFraction 7 + StartRoot 65 EndRoot Over 2 EndFraction
Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:
<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.
8 x 8 = 64
Well thats much too high, We'll try a lower number.
4 x 4 = 16
Just a little higher.
5 x 5 = 25
Since 5 times itself equals 25 that makes it the sqrt.
So, the √ 25 is 5.
the axis of symmetry is x=2
