Which factors can be multiplied together to make the trinomial 5x2 + 8x – 4? Check all that apply.

(x + 1)

(2x + 1)

(x + 2)

(5x + 1)

<span>(5x – 2)

Solution :

By multiplying (5x - 2) and (x + 2), the given trinomial will be obtain as follow. 
 </span>(5x - 2) * (x + 2) = (5x * x) + (5x * 2) - (2 * x) - (2 * 2)
=  <span>5x^2 + 10x - 2x - 4
= </span>5x^2 + 8x - 4

Answer:

Multiplying (5x+2) and (x+2) we can get the trinomial 5x^2+8x-4.

Step-by-step explanation:

The given trinomial is,

=5x^2+8x-4

By middle term factorization,

=5x^2+10x-2x-4

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

=(5x+2)(x+2)

Therefore, multiplying (5x+2) and (x+2) we can get the trinomial 5x^2+8x-4.

Klio2033 [76]

Explanation:

We can find the slope by solving for y.

  3x +2y +7 = 5x +3y +10

  -2x -3 = y . . . . . . . . . . . . . add -5x-10-2y to both sides of the equation

In this form, the slope (m) is the coefficient of x, -2. Hence m = -2.

__

<em>Alternate solution</em>

A graph of the equation shows it has an x-intercept of -1.5 and a y-intercept of -3. The slope (m) is then "rise" divided by "run", or ...

  m = rise/run = -3/1.5

  m = -2
