Question

Choose the value for x that makes the open sentence true.

8 + 3 • x = 22 + x2

Answer 1

is that 8 + 3 = 22 + x^2

Answer 2

oops its should be 2 squared plus x squared

Answer 3

8 + 3x = 2^2 + x^2 ?

Answer 4

We can turn that into a quadratic equation:

x^2 -3x + (8 + 4)

= x^2 - 3x + 12

I think you'll have to use the quadratic formula here.

Answer 5

whats the value of x

Answer 6

You need to use the quadratic formula to figure it out

Answer 7

i dont know how

Answer 8

We had x^2 - 3x + 12, so

a = 1
b = -3
c = 12

Plug them into the formula to solve for x
