As long as you're asking for help, you may as well ask a graphing calculator that can actually tell you the answer.
Solutions are (x, y) = (-6, 312) and (6, 312).
_____
Divide the second equation by 2, then substitute the expression for y into the first equation. Solve the quadratic for x.
.. 10x^2 -(8x^2 +24) = 48
.. 2x^2 -72 = 0
.. 2(x -6)(x +6) = 0
.. x = -6 or 6
.. y = 8x^2 +24 = 8*36 +24 = 312 . . . for either value of x
Answer: 0.625
Step-by-step explanation:
Answer:
(x + 5)^2
Step-by-step explanation:
Learn to recognize perfect squares. x^2+ 10x + 25 is a perfect square of a binomial: x^2+ 10x + 25 = (x + 5)^2.

EXPLANATION
The given function is
The potential rational roots are all factors of -3 expressed over all factors of 5.
These are:
Since the root of f(x) at P is closer to 1 that zero and it is positive , that potential may be
