Visualize (x+2)(x+3).
We know that:
(x+a)(x+b)=x2+x(a+b)+ab
Plug in a=2 and b=3
(x+2)(x+3)=x2+x(2+3)+2×3
=x2+2x+3x+6
5x or 3x+2x( addition of both 3x and 2x )
Which of the following shows the visualization of the subtraction of 3x from 9x?
Which of the following shows the visualization of the addition of 3x and 9?
