❗ANSWER+EXPLANATION=100POINTS+BRAINLIEST❗<br>solve: (x+2)(5x-1)=0<br>thanks)​
IrinaVladis [17]

The solution to the given quadratic equation is;

x = -2 and x = 1/5

<h3>Roots of quadratic Equation </h3>

We are given the quadratic function;

(x + 2)(5x - 1) = 0

In quadratic functions, when it is expressed as;

(x + a)(x - b) = 0, what this means is that the factors of the quadratic equation or polynomial are; (x + a) and (x - b)

What that means is that the roots will be gotten from;

(x + a) = 0 and (x - b) = 0

Thus, applying the concept above on roots of a polynomial to our question, we have;

(x + 2) = 0 and 5x - 1 = 0

Solving them gives us;

x = -2 and x = 1/5

Please please please help me with this question<br>which is the correct answer​
Oksi-84 [34.3K]

Answer:

  (a)  (a² +3a -1)(a² -3a -1)

Step-by-step explanation:

The constant term of the product of the factors will be equal to the product of their constants. Since you want that product to be +1, the signs of the factor constants must be the same. That eliminates choices (c) and (d).

__

To tell which of choices (a) and (b) is correct, we can compute the squared term in their product. Let's do it in a generic way, with the constant (±1) being represented by "c".

We want the a² term in the product ...

  (a² +3a +c)(a² -3a +c)

That term will be the result of multiplying both sets of first and last terms, and adding the product of the middle terms:

  (a²·c) +(a²·c) -9a² = a²(2c-9)

So, we want the factor (2c-9) to be -11, which means c=-1, not +1.

The correct factorization of the given expression is ...

  (a² +3a -1)(a² -3a -1) . . . . matches choice A
