Correct Question
- X²-11x+30 do it by middle term spilliting
- A polynomial
- X²-11x+30
- Factors of the polynomial
.
Method-1
- X²-11x+30
- we have to spilt the middle term in such a way that the product become 30 and sum become -11x
X²-11X+30
=>X²-5x-6x+30
=>x(x-5)-6(x-5)
=>(x-5) (x-6)
=>x=5,4
Method -2
By quadratic formula
Here
a=1
b=-11
C=30
¶utting values
Taking X as +
=>{11+1}/2
=>6
Taking X as +
=>{11-1}/2
=>5
