Question

3a^2 - 5a + 11=?
pls solve

Answer 1

Answer:

STEP
1
:
Equation at the end of step 1
(3a2 - 5a) + 11
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 3a2-5a+11

The first term is, 3a2 its coefficient is 3 .
The middle term is, -5a its coefficient is -5 .
The last term, "the constant", is +11

Step-1 : Multiply the coefficient of the first term by the constant 3 • 11 = 33

Step-2 : Find two factors of 33 whose sum equals the coefficient of the middle term, which is -5 .

-33 + -1 = -34
-11 + -3 = -14
-3 + -11 = -14
-1 + -33 = -34
1 + 33 = 34
3 + 11 = 14
11 + 3 = 14
33 + 1 = 34

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Final result :
3a2 - 5a + 11
