Answer:
Factorize of x³ - 39x + 70 is => (x - 2) (x - 5) (x + 7) .
Step-by-step explanation:
Hey Mate,
Factorize of x³ + 39x + 70 is
=> x³ − 2x² + 2x² + 4x + 35x + 70
=> x² (x − 2) + 2x (x + 2) +35 (x + 2)
Error in Equation
Correct Equation is => x³ - 39x + 70
Now,
=> x³ − 2x² + 2x² - 4x - 35x + 70
=> x² (x − 2) -2x (x - 2) -35 (x - 2)
=> (x − 2) (x² + 2x - 35)
=> (x − 2) (x² + 7x - 5x - 35)
=> (x - 2) {x (x + 7) - 5 (x + 7)}
=> (x - 2) (x - 5) (x + 7) .
Factorize of x³ - 39x + 70 is => (x - 2) (x - 5) (x + 7) .
