Use consensus property to add a subexpression which will you simplify the expression
x1 x4' + x2 x4 + x1 x2'

Hi. The subexpression is:

1/

Step-by-step explanation: Adding the exponents of x the equation is as follows :

if you multiply by the subexpression 1/, the equation would be simplified, as follow:

()*(1/) = 1

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
