and (–x+2/7x²) and(7x–x²)
and verify the result for x=3
​

Answer 1

Answer:

$\huge\bigstar\underbrace{\mathtt\red{A} \mathtt\purple{N} \mathtt\green{S}\mathtt\blue{W} \mathtt\blue{E} \mathtt\orange{R}}\bigstar$

Step-by-step explanation:

ANSWER

$\rightarrow \: ( - x + \frac{2}{7}x {}^{2} ) \times \: (7x - x {}^{2} )$

$- 7x {}^{2} + x^3 \: + \frac{2}{x} - 2$

Hence, this is the product.......

Substituting x= 3 in the following product......

$- 7(3) {}^{2} + 3^3 + \frac{2}{3} - 2$

According to me, the answer is $\frac{-112}{3}$
