Answer:
6x³ - 17x² + 11x - 2
Step-by-step explanation:
The cubic polynomial in general form is:
- ax³+bx²+cx+d = (x-x1)(x-x2)(x-x3)
zeroes are
then we can get the polynomial as:
- (x-2)(x-1/3)(x-1/2)=0
- (x-2)(3x-1)(2x-1)=0
- (3x²-x-6x+2)(2x-1)=0
- (3x²-7x+2)(2x-1)=0
- 6x³-3x²-14x²+7x+4x- 2=0
- 6x³ - 17x² + 11x - 2= 0
So the required polynomial is:
Answer:
x = -5, y = 7 or you can say (-5, 7)
Answer:
Sara's mother age : 40 years
Sara's age : 10 years
Step-by-step explanation:
Let Sara's mother age be x
and Sara age be y
Given , Sara's mother is now four time as old as Sara
• x = 4y ...1
also, in five years , she will be three times as old as Sara
In five years , Sara's mother age :- ( x + 5 )
Sara age :- ( y + 5 )
according to the question,
x + 5 = 3 ( y + 5 )
x + 5 = 3y + 15
x - 3y = 10 ... 2
putting value of x from 1 into 2
4y - 3y = 10
y = 10
putting y value in 1
x = 4y = 4 ( 10 ) = 40
So, Sara's mother age is 40years
and Sara's age is 10years .
