Respuesta :
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)
(5x – 2)
Solution :
By multiplying (5x - 2) and (x + 2), the given trinomial will be obtain as follow.
(5x - 2) * (x + 2) = (5x * x) + (5x * 2) - (2 * x) - (2 * 2)
= 5x^2 + 10x - 2x - 4
= 5x^2 + 8x - 4
(x + 1)
(2x + 1)
(x + 2)
(5x + 1)
(5x – 2)
Solution :
By multiplying (5x - 2) and (x + 2), the given trinomial will be obtain as follow.
(5x - 2) * (x + 2) = (5x * x) + (5x * 2) - (2 * x) - (2 * 2)
= 5x^2 + 10x - 2x - 4
= 5x^2 + 8x - 4
Answer:
Multiplying [tex](5x+2)[/tex] and [tex](x+2)[/tex] we can get the trinomial [tex]5x^2+8x-4[/tex].
Step-by-step explanation:
The given trinomial is,
[tex]=5x^2+8x-4[/tex]
By middle term factorization,
[tex]=5x^2+10x-2x-4[/tex]
[tex]=5x(x+2)-2(x+2)[/tex]
[tex]=(5x+2)(x+2)[/tex]
Therefore, multiplying [tex](5x+2)[/tex] and [tex](x+2)[/tex] we can get the trinomial [tex]5x^2+8x-4[/tex].
