You cant solve this because there is no matching variables like for example:

x^2-3xy+2x-2y-4+xy-5x+6y+8 and i solved this which the answer is x^2-3x+4y-2xy+2 because there are matching variables.

Input data

In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H). In a formula, it is written as 'sin' without the 'e':

$\begin{gathered} \sin A=\frac{5}{18} \\ \sin A=0.277 \end{gathered}$

What are the solutions for x when y is equal to 0 in the following quadratic

lawyer [7]

Answer:

D) x = -12 or x = 2

Step-by-step explanation:

The given quadratic equation is:

$y=x^2+10x-24$

When y=0, we obtain:

$x^2+10x-24=0$

We split the middle term with -2, 12 because their product is is -24 and their sum is 10.

$x^2-2x+12x-24=0$

We factor by grouping to obtain:

$x(x-2)+12(x-2)=0$

$(x-2)(x+12)=0$

Either $(x-2)=0$ or $(x+12)=0$

Either $x=2$ or $x=-12$
