Question

do u agree with solutions, explain?
a)x^-3×x^-5=x^+15
b)3x^-1=1/3x​

Answer 1

Answer:

no i dont

Step-by-step explanation:

1. Because

(x²-3)×(x²-5)=x²+15 = Question

we use the distributive property

x⁴-5x²-3x²+15=x²+15

x⁴-8x²+15=x² + 15

I dont agree on the first one as the answers are different

b) 3x²-1=1/3x

3x²-1

we can do this by the 3rd identity (a²-b²) = (a+b) (a-b)

(3x)²- (1)²

we get

(3x+1) ( 3x-1)

plz note that these answers wont be correct i just tried it out but i dont think its correct

sorry
