Question

x3+39x+70
please facorise it

Answer 1

3x + 39x =42x

and

42x + 70 = 14(3x+5) 

since 14 is the common factor

Answer 2

Answer:

The factories of x³ - 3x + 70 is ( x - 2 ) × ( x - 5 ) × ( x + 7 )

Step-by-step explanation:

Hey Mate,

When i try to solve this equation i get hang at last. so after that i find a small mistake in the equation . So, please make it correct.

Correction in Equation : x³ - 3x + 70

=> x³ - 3x + 70

When we divide x³ - 3x + 70 by x -2 so we get x² + 2x - 35.

So,

=> ( x - 2 ) × ( x² + 2x - 35 )

Now we can easily solve the that second equation.

So, The factories of x³ - 3x + 70 is

=>  ( x - 2 ) × ( x - 5 ) × ( x + 7 )
