3. How many solutions does the system have? }
Sy = x2 + 4x – 2
1 y = 2x+1

Answers

Answer:

Hence two solution of expression

I.e x= 1 , - 3

Step-by-step explanation:

Given as :

y = x² + 4 x - 2

And y = 2 x + 1

Solving these equation

x² + 4 x - 2 = 2 x + 1

or, x² + 4 x - 2  - 2 x -  1 = 0

Or, x² + 2 x - 3 = 0

Or,  x² + 3 x - x - 3 = 0

Or, x ( x + 3 ) -1 ( x + 3 )= 0

Or, ( x + 3 ) ( x - 1 ) = 0

or, x = - 3  And x = 1

Hence two solution of expression Answer

If a quadratic equation with real coefficients has a discriminant of 3 then the two roots must be

Answers

In a quadratic equation

q(x) = ax^2 + bx + c 

The discriminant is = b^2 - 4ac

We have that discriminant = 3

If b^2 - 4ac > 0, then the roots are real.

If b^2 - 4ac < 0 then the roots are imaginary

In this problem b^2 - 4ac > 0   3 > 0

then the two roots must be real
