Solve for x in the equation x^2 - 14x + 31 = 63?
<h3><u>Answer:</u></h3>
The value of x for given equation is x = 16 or x = -2
<h3><u>Solution:</u></h3>
Given that equation is
To find: value of "x"
<u>Subtract 63 from both sides we have:</u>
Now we will factor our given quadratic equation by splitting the middle term.
-14x can be splitted as -16x + 2x
<u>Take "x" as common from first two terms and "2" as common from last two terms</u>
<u>Take (x-16) common we have:</u>
Equating the terms to 0,
x - 16 = 0 or x + 2 = 0
x = 16 or x = -2
Therefore, the value of x are: 16 and -2
6/1 ÷ 3/5
You always flip the second fraction and turn the ÷ to a ×.
6/1 × 5/3 simplified to 10/1 (or 10)
Answer : 10
