Which expression is equal to
which expression is equal to ( 2x2 – 5)(3x2 +1),
o – 6xt – 13x² – 5
6x4 – 13x2 – 5
- 6xt – 17x² – 5
–6x2 – 17x – 5
next

6x^4-13x^2-5

Step-by-step explanation:

(2x^2-5)(3x^2+1)

6x^4+2x^2-15x^2-5

6x^4-13x^2-5

s = 1

Step-by-step explanation:

I moved all terms to the left:

2(8s-1)-(14s)=0

I added all the numbers together, and all the variables

-14s+2(8s-1)=0

I multiplied parentheses

-14s+16s-2=0

I added all the numbers together, and all the variables

2s-2=0

I moved all terms containing s to the left, all other terms to the right

2s=2

s=2/2

s=1
