(9) The solution is x = 1 and x = 5
(10) The solution is x = 12 and x = -8
Explanation:
(9) The given expression is![(x+3)(x-3)=6 x-14](/tpl/images/0560/9428/6b4b1.png)
We need to determine the solution of the equation.
The term
can be expanded using the formula, ![(a+b)(a-b)=a^{2}-b^{2}](/tpl/images/0560/9428/baab8.png)
Thus, we have,
Solving the quadratic equation, we get,
The solution of the quadratic equation are x = 5 and x = 1
(10) The given expression is![3 x^{2}-12 x-288=0](/tpl/images/0560/9428/8797d.png)
We need to determine the solution of the equation.
Let us solve the equation using the quadratic formula,
where![a=3, b=-12, c=-288](/tpl/images/0560/9428/cda25.png)
Thus, we have,
Simplifying the terms, we have,
Thus, the roots are
Thus, the solution is x = 12 and x = -8
