Question

(2x-0.4y)(1.3x-4y) find the product​

Answer 1

⇒ $2.6\times{x^{2}} +   1.6 \times y^{2} -  8.52 xy$

Step-by-step explanation:

⇒ $(2x - 0.4y)(1.3x - 4y)$

multiply,

⇒ $2.6\times(x)^{2} - 0.52\times{xy} - 8xy + 1.6\times(y)^{2}$

⇒ $2.6\times(x)^{2} - 8.52xy +  1.6\times(y)^{2}$

⇒ $2.6\times(x)^{2} +   1.6\times(y)^{2} -  8.52xy$
