I simplified it to, 2x^2 - 12+13
Step-by-step explanation:
x² + 4x - 32
= (x + 8)(x - 4).
Hence the x-intercepts are (-8, 0) and (4, 0). (B)
----------------------------------------------------------
Define x :
----------------------------------------------------------
Let one of the number be x. The other number is x + 2.
----------------------------------------------------------
Construction Equation :
----------------------------------------------------------
The sum of the square of the two number is 202.
----------------------------------------------------------
Solve for x :
----------------------------------------------------------
x = -11 is rejected, since it only want positive integer.
----------------------------------------------------------
Find the two numbers :
----------------------------------------------------------
x = 9.
x + 3 = 11
----------------------------------------------------------
Answer: The numbers are 9 and 11.----------------------------------------------------------
