Question

(1.5x^2-0.3y^2)(1.5x^2+0.3y^2)evaluate​

Answer 1

Answer:

(2.25x^4)-(0.09y^4)

Step-by-step explanation:

We know,

(a+b)(a-b)=a^2-b^2

using this formula,

a=1.5x^2

b=0.3y^2

so a^2=(1.5x^2)(1.5x^2)=2.25x^4

and b^2=(0.3y^2)(0.3y^2)=0.09y^4

therefore the answer is (2.25x^4)-(0.09y^4).
