Step-by-step explanation:
Let's factorize x² - [tex]\frac{y ^{2} }{100}[/tex]
- x²-[tex]\frac{y^{2} }{100}[/tex]
- x² -([tex]\frac{y^{2} }{10^{2} }[/tex])
- (x+[tex]\frac{y}{10}[/tex])(x-[tex]\frac{y}{10}[/tex])
Let's factorize 9x²+6xy+y²
- 9x²+6xy+y²
- (3x)²+2*3x*y+y²
- (3x+y)²
evaluate 99³
- 99³
- (100-1)²(100-1)
- (100²-2*100+1) *99
- (10000-201)*99
- 9799*99
- 970101
evaluate 95*96
