KOLEKSI SIRI PERTAMA QUANTUM COOL-ACTIVE: MATHEMATICS SIMPLIFIED : FROM BASICS TO BRILLIANCE

1. Write the equation in standard form ax²+bx+c= 0

2. Identify the coefficients (a,b and c)

3. Find two numbers such that :

i) ( 1 st no)( 2 nd no) = ac

ii) 1 st no + 2 nd no = b

4. Rewrite the middle term ax² + mx + nx + c = 0 ,

where m = 1 st no, n = 2 nd no

5. Group the terms, take the common factor out,

then simplify

6. Apply the zero product property ax+m= 0 ,

ax+n= 0

7. Solve for x to find the roots.

2. Select 3 ( fx- 570 es

plus)

3. Enter the values for

a, b, and c

4. Press Equals
