Splitting the middle term Method | Class 10

Quadratic Equation

1. SPLITTING THE MIDDLE TERM METHOD WELCOME TO MATTER STUDY

2. FIND THE ROOTS OF THE QUADRATIC EQUATIONS BY FACTORISATION: (EX. 4.2 Q 1, CLASS 10 TH NCERT) ( i )  

3. NOW, WE TAKE THE FIRST PART   Rough Work / Think in Mind As we know that, The general quadratic equation i s   In Splitting the Middle Term Method, Multiply a and c without considering sign And make factors of multiplied result

4. Now Come to Our Example:   Step 1: Multiply coefficient of (i.e . 1) and 10 1×10= 10   Now, we factorize this result 10 = 5,2 10 = 1,10 We consider 5 and 2, because we have to subtract

5. Step 2:     NOW TAKING COMMON x AND 2       Our Roots Are: X-5=0, x=5 X+2=0, x=-2
