Difficult Passport to Advanced Math Problem
with Solution
Today I would like to provide a solution for the SAT math problem I posted on Friday.
Level 5 Passport to Advanced Math
y = x2 + 5x + 6
7x + 4 – y = 0
How many solutions are there to the system of equations above of the form (x,y), with x a real number?
(A) 0
(B) 1
(C) 2
(D) More than 2
* Solution by substitution: We solve the second equation for y by adding y to each side of the equation:
7x + 4 = y
We now replace y by 7x + 4 in the first equation to get
7x + 4 = x2 + 5x + 6
We now add –7x – 4 to each side of the equation to get
0 = x2 – 2x + 2
The equation x2 – 2x + 2 = 0 has discriminant
b2 – 4ac = (–2)2 – 4 ⋅ 1 ⋅ 2 = 4 – 8 = –4
Since the discriminant is negative, there are no real values of x that satisfy the equation. So, the answer is choice A.
Notes: (1) To learn more about the discriminant of a quadratic equation, see the following post: The Discriminant of a Quadratic Equation
(2) For one method of solving quadratic equations, see the following post: The Quadratic Formula
