expand (4x^2+5y^2)i+4xyj

expand

(4 x^{2} + 5 y^{2}) i + 4 x y j

4 j x y + (4 x^{2} + 5 y^{2}) i

Solution steps

(4 x^{2} + 5 y^{2}) i + 4 x y j

= i (4 x^{2} + 5 y^{2}) + 4 j x y

Expand

i (4 x^{2} + 5 y^{2}) : 4 x^{2} i + 5 i y^{2}

= 4 x^{2} i + 5 i y^{2} + 4 j x y

Rewrite in standard complex form:

4 j x y + (4 x^{2} + 5 y^{2}) i

= 4 j x y + (4 x^{2} + 5 y^{2}) i

(2, 3) (- 3, 1) y (- 1, - 3)

x \cdot y^{2} - (x^{3} + y^{3}) d x

(t^{2} + b t + c) (t^{2} + d t + e)

\frac{200}{s ( s ^{3} + 6 s ^{2} + 11 s + 6 )}

\frac{s + 10}{( s + 2 ) ( s ^{2} + 6 s + 25 )}
