<span>Numbers
are those integers used in a certain equation. For example: 5, 10, 5/4, 11,
.1542, -100; these are all numbers despite its differences, may it be negative
or positive number, may it fraction or decimals.
Variables refer to the letters used in a certain equation. For example, 5x, x
is the variable used. This is usually used to represents unknown numbers.
And lastly operation and symbols, Operations are used to add, subtract, divide
and multiply the given equation. Symbols are used to get the square root of a
given number and more.</span><span>

<span>I think you meant 6x²+13x-5 so first thing we have to do is factor it which is really quite tricky with this kind of trinomial so first take ac which is 6 times -5 so -30 now figure out factors of -30 that will add up to 13 how about 15 and -2 now that we have the factors write the equation again</span>
<span /><span> 6x²+15x-2x-5 </span>split the equation in half<span />
<span>6x²+15x -2x-5 so out of the first equation we can pull a 3x out</span>
<span>3x(2x+5) and out of the second we can pull a negative 1</span>
<span>3x(2x+5) -1(2x+5) rewrite it</span>
<span>(3x-1)(2x+5) so the 3x-1 is the factor we already had so the other side is (2x+5)</span>

1) the domain is x∈[0;+∞);
2) the solution is:
3) finally, the solution with the domain is:
x∈[0;100].
Answer: x = 6
Step-by-step explanation:
X - (-4) = 10
X + 4 = 10
X = 10 - 4 = 6
