Question

29x²-490x-390 solve the equation

Answer 1

29x2-490x-390

Final result :

29x2 - 490x - 390

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(29x2 - 490x) - 390

Step 2 :

Trying to factor by splitting the middle term

2.1 Factoring 29x2-490x-390

The first term is, 29x2 its coefficient is 29 .

The middle term is, -490x its coefficient is -490 .

The last term, "the constant", is -390

Step-1 : Multiply the coefficient of the first term by the constant 29 • -390 = -11310

Step-2 : Find two factors of -11310 whose sum equals the coefficient of the middle term, which is -490 .

-11310 + 1 = -11309

-5655 + 2 = -5653

-3770 + 3 = -3767

-2262 + 5 = -2257

-1885 + 6 = -1879

-1131 + 10 = -1121

For tidiness, printing of 26 lines which failed to find two such factors, was suppressed

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

29x2 - 490x - 390
