(x2 – 2x +3)(3x2 + 5x – 7) – (3x2 – 2x + 5)(2x + 5)
Answers
Well Algebra!!!! Great question. I've texted a very clear step by step clear explanation. Read it carefully and try to find the ans
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
STEP
1
:
Equation at the end of step 1
(2x - 5) • ((3x2 + 5x) - 7)
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 3x2+5x-7
The first term is, 3x2 its coefficient is 3 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -7
Step-1 : Multiply the coefficient of the first term by the constant 3 • -7 = -21
Step-2 : Find two factors of -21 whose sum equals the coefficient of the middle term, which is 5 .
-21 + 1 = -20
-7 + 3 = -4
-3 + 7 = 4
-1 + 21 = 20
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(2x - 5) • (3x2 + 5x - 7)
