Y= x^2 + - 10
Y= 2x - 4

Replace all occurrences of +− with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because  1⋅−1 = −1

Y=x²−10, Y=2x−4

Eliminate the equal sides of each equation and combine.

x²−10 = 2x−4

Solve x²−10 = 2x−4 for x.

x= 1+√7, 1−√7

Evaluate Y when x = 1 + √7.

Y =−2 + 2√7

Evaluate Y when x = 1 − √7.

Y=−2 − 2√7

The solution to the system is the complete set of ordered pairs that are valid solutions.

(1+√7,−2+2√7)

(1−√7,−2−2√7)

The result can be shown in multiple forms.

Point Form:

(1+√7, −2+2√7), (1−√7, −2−2√7)

Equation Form:

x= 1+√7, y= −2+2√7

x= 1−√7, y= −2−2√7
