Question

Solve the problem

(2x-9) (2x+7)

​

Answer 1

Answer:

4x^2-4x-63

Step-by-step explanation:

First, we need to distribute. When we distribute, we get:

4x^2+14x-18x-63

Next, we need to combine like signs. When I do this, we get:

4x^2-4x-63

So, our quadratic equation is 4x^2-4x-63. Attached below is what the quadratic equation would look like on a graph.

Answer 2

Answer:

x=9/2 ; x=-7/2

Step-by-step explanation:

as it is already simplified we cannot simplify it more. And Use (Zero product law)

(2x-9) (2x+7)

(2x-9) =0 ; (2x+7)=0

x=9/2 ; x=-7/2
