5. find the value of (a+B) & (aB) for
the following equation, X2 - 11x+33 = 0
Answers
Answer:
a + B = -b/a = 11
aB = c/a = 33
Answer:
Factoring x2-11x+33
The first term is, x2 its coefficient is 1 .
The middle term is, -11x its coefficient is -11 .
The last term, "the constant", is +33
Step-1 : Multiply the coefficient of the first term by the constant 1 • 33 = 33
Step-2 : Find two factors of 33 whose sum equals the coefficient of the middle term, which is -11 .
-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
