Solve the system of equations..
y=x +45
y= 5x + 13

x = 8

y = 53

Step-by-step explanation:

Sub y = x + 45 into the second equation

x + 45 = 5x + 13

Rearrange by collecting the like terms

45 - 13 = 5x - x

32 = 4x

Divide both sides by 4

x = 8

Sub x = 8 into first equation (y = x + 45)

y = 8 + 45

y = 53

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
