5 x² -7x +3 what is the answer
Answers
Answer:
5x² - 7x + 3
Step-by-step explanation:
STEP
1
:
Equation at the end of step 1
(5x² - 7x) + 3
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 5x² -7x+3
The first term is, 5x² its coefficient is 5 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is +3
Step-1 : Multiply the coefficient of the first term by the constant 5 • 3 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -7 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8
5 + 3 = 8
15 + 1 = 16
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
5x² - 7x + 3
