Factor the trinomial step by step & explain 2x^2+ 5x + 3
Colt1911 [192]

Answer:

One way to factor equation is to find the zeros. Its obvious that x=-1 is solution for this. So one factor is (x+1)

the next factor should include 2x at first (because we have 2x^2 in the equation which can not be made any other way)

Let's suppose the factor is (x+1)(2x+b)

Since we do not know what is b open the brackets 2x^2+bx+2x+b. If this is equal to 2x^2+5x+3 then b=3. We are left with (x+1)(2x+3)=2(x+1)(x+3/2)

Would go for other shorter solutions, but they require some deeper understanding like Horner's scheme,Fermat's Theorem or even deeper which I assume You will not understand)

If y is directly proportional to x squared <br> and y = 3 when x = 2, what is y when x = 8?
Anestetic [448]

Answer:

<u><em>y = 63</em></u>

Step-by-step explanation:

<em>y is directly proportional to x²</em>

<em>As given,</em>

<em>when y = 3 => x = 2</em>

<em>So, 3 = 4 - 1</em>

<em>Which means the relation can be written as :-</em>

<em>y = x² - 1</em>

<em></em>

<em>Substituting x = 8</em>

<em>y = (8)² - 1</em>

<em>y = 64 - 1</em>

<u><em>y = 63</em></u>
