y = r sin theta
sin theta = y/r
r sin theta = 4 Substituting for sin theta:-
r * (y/r) = 4
y = 4 is the answer
The correct answer is option D.Which is ( x - 1 ).
<h3>What is a quadratic equation?</h3>
It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
The solution of the given quadratic equation will be:-
-2x² - 22x + 24 = 0
x ² + 11x - 12 = 0
x² + 12x - x + 12 = 0
x ( x + 12 ) -1 ( x + 12 ) = 0
( x -1 ) ( x + 12 ) = 0
Therefore the correct answer is option D.Which is ( x - 1 ).
