Question

(x+4)(x+1)-(x-1)(x-2) along with process​

Answer 1

Answer:

8x+2

Step-by-step explanation:

(x+4)(x+1)-(x-1)(x-2)

= [(x+4)(x+1)]-[(x-1)(x-2)]

= [x(x+1)+4(x+1)] - [x(x-2)-1(x-2)]

= [x²+x+4x+4] - [x²-2x-x+2]

= [x²+5x+4] - [x²-3x+2]

= x²+5x+4 - x²+3x-2

= x²-x²+5x+3x+4-2

= 8x+2

Answer 2

Step-by-step explanation:

=(x+4)(x+1)-(x-1)(x-2)

=x(x+1)+4(x+1)-x(x-1)-1(x-2)

=x²+x+4x+4-x²+x-x+2

=x²-x²+5x+4+2

=5x+6
