Question

Split x² + x - 402

Quality Answer Needed !!!!!​

Answer 1

Answer:

Hey!

x^2 + x - 402 = 0

x^2 +x = 402

X + X = √402

2x= 20.34

X = 10.17

hope it helps u ✌️

Answer 2

Step-by-step explanation:

x² + x - 402

By middle term splitting, we can't factorise x²+x-402 because there are no factors of -402 whose sum is 1.

[in middle term splitting we multiply 'c' with 'a' of the quadratic polynomial, then split 'b' to 2 numbers whose product will be equal to the product of 'c' and 'a' and will add up to the co-efficient of 'b'].  

In this case, no factors of -402 add to give the sum of 1.

So, it is not possible to split x²+x-402.

Thank you.
