Question

Solving polinomial(2x+8)(2x-1)​

Answer 1

=4x2+14x−8

Explanation:

(2x+8)(2x−1)

=(2x+8)(2x+−1)

=(2x)(2x)+(2x)(−1)+(8)(2x)+(8)(−1)

=4x2−2x+16x−8

=4x2+14x−8

I hope this helps! :]

Answer 2

4x²+14x-8 ( multiplying)

x=-4 , x=1/2 ( find solution)

Explanation:

(2x+8)(2x-1)​

start :

2x*2x=4x²

2x*-1 = -2x

8*2x=16x

8*-1=-8

add the results : 4x²-2x+16x-8 = 4x²+14x-8

If you mean find the solution :

(2x+8)(2x-1)​=0

2x+8=0

x=-8/2=-4

OR 2x-1=0

then x=1/2
