Question

Find the solution to the system.
1. Y=x^2+5x+6
Y=4x+12

Find the solution to the system.
2. Y=x^2-3x-1
Y=8x-1

Answer 1

I hope this helps you



1)


4x+1=x^2+5x+6


x^2+x-6=0

x +3

x -2

(x+3)(x-2)=0

x+3=0 x= -3 y=4x+1=4. (-3)+1=-12+1= -11

x-2=0 x=2 y=4x+1=4.2+1=8+1=9



2)


8x-1=x^2-3x-1

x^2=11x

x.x=11.x

x=11

y=8x-1=8.11-1=88-1=87
