Answer:

Step-by-step explanation:

With no middle term, we factor the quadratic into two binomials of the form (x+a)(x-a) where a is the same number. 64 factors only into 8(8) where the factors are equal. We write in the form (x+8)(x-8).

To find the root or x-intercept, we set equal to 0.

(x+8)(x-8)=0

x=-8,8.

Given the following system of equations: 2x + 6y = 12 4x + 3y = 15 Which action creates an equivalent system that will eliminate

ozzi

Answer:

Multiply the second equation by −2 to get −8x − 6y = −30.

Step-by-step explanation:

{2x + 6y = 12

{4x + 3y = 15

{2x + 6y = 12

{−8x − 6y = −30 >> New Equation

* Doing this will give you additive inverses of −6y and 6y, which result in 0, so they are both ELIMINATED.

** [3, 1] is your solution.
