Question

Explain Property (x+a)(x+b)

Answer 1

Answer:

(x+a)(x+b)

x(x+b)+a(x+b)

x²+ xb + xa + ab

Answer 2

answer:

x^2 + (a+b)x + ab

explanation:

In the two terms, First you have to multiply both the x. So x multiplied with x is x^2.

Next you should multiply b and x. So you get bx.

Next multiply a and x and you get ax.

Finally multiply a and b and you get ab.

Then add all of them,

x^2 + bx + ax + ab

=> x^2 + (a+b)x + ab
