Find the solutions of and

x is     AND

y =      And

Step-by-step explanation:

Given two equations are :

y = x² + 2         And

y = x + 1

So, the equation can be written as

x² + 2  =  x + 1

Or, x² - x + ( 2 - 1) = 0

Or, x² - x + 1 = 0

This is in the form of quadratic equation

So,   Roots of equation x be :

     x =

Or, x =

Or , x =

Hence the two value of x is     AND

So , y =      And

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
