:
Equation at the end of step
2
:
((23r2 - 12r) + 4) - (3r2 + 5r - 1)
STEP
3
:
Trying to factor by splitting the middle term
3.1 Factoring 5r2-17r+5
The first term is, 5r2 its coefficient is 5 .
The middle term is, -17r its coefficient is -17 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 5 • 5 = 25
Step-2 : Find two factors of 25 whose sum equals the coefficient of the middle term, which is -17 .
-25 + -1 = -26
-5 + -5 = -10
-1 + -25 = -26
1 + 25 = 26
5 + 5 = 10
25 + 1 = 26
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
5r^2 - 17r + 5
r^2
