Question

please help me out with this problem. ​

Answer 1

Step-by-step explanation:

we can do this by using splitting terms,

3x²+5x-8 2 numbers which-

Sum should be 11x

Product should be 24x

Two numbers are 3 and 8

3x²+3x-(8x-8)

Now, we can do it by regrouping method-

= (3x²+3x)-(8x-8)

= (3x²+3x)-(8x+8)

By using common method-

= 3x(x+1)-8(x+1)

= (x+1) (3x-8) (Ans)

Q2. p(x) = x²-3x

Zeros of polynomial= By equaling to 0

x²-3x=0

x² =0+3x

x² = 3x

p(x) = 3x/x²

Q3.Sorry, I am not able to do.

Q4 0.2343434......- It indicates that it is a irrational numbers, so, to indicate this in p/q

2343434

1000000

Q5. We can find it by using splitting terms,

2x²-4x+2 Two numbers-

Sum should be 4

Product should be 4

2x²-(2x+2x)+2

2x²-(2x-2x)+2

(2x²-2x)-(2x+2)

By using regrouping method,

(2x²-2x)-(2x-2)

=2x(x-1)-2(x-1)

= (x-1) (2x-2)

Zeros of polynomial= By equaling it with 2

p(x) = (x-1) (2x-2)=0

x×2x =0+1+2

2x² = 3

p(x) = 3/2x²
