expand x^2+2x+1+y(x+1)

expand

x^{2} + 2 x + 1 + y (x + 1)

x^{2} + 2 x + 1 + x y + y

Solution steps

x^{2} + 2 x + 1 + y (x + 1)

Apply the distributive law:

a (b + c) = ab + a c

y (x + 1) = y x + y \cdot 1

= x^{2} + 2 x + 1 + y x + y \cdot 1

Simplify

y x + y \cdot 1 : x y + y

= x^{2} + 2 x + 1 + x y + y

\frac{24}{12}

(f + g) (2)

6 \times 9

(4 a^{2} - 7 ab) (2 a^{3} b)

\frac{3}{4} \div 4
