y6x10 yx22 solve the following system of equation algebraica
y=-6x-10
y=x^2-2
solve the following system of equation algebraically
Solution
given equations
y=-6x-10
y=x^2-2
there are two y equations given , equate them
6x-10 = x^2 -2
x^2 -2 -6x +10=0
x^2 -6x +8=0
x^2 -2x-4x+8=0
x(x-2)-4(x-2) =0
(x-2) (x-4)=0
so (x-2) =0 or (x-4)=0
x=2 or x=4
y value when x =2, y=2
y value when x=4 ,y =14
small value of x =2
large value of x=4
