Question

x^2+ 5x+9
factorie it

​

Answer 1

Step-by-step explanation:

comparing the equation with ax2 +bx +c

then quadratic formula used

Answer 2

Step-by-step explanation:

Factoring x2-5x-9

The first term is, x2 its coefficient is 1.

The middle term is, -5x its coefficient is -5.

The last term, "the constant", is -9

Step-1: Multiply the coefficient of the first term by the constant 1 • -9 = -9

Step-2: Find two factors of -9 whose sum equals the coefficient of the middle term, which is -5.

-9 + 1 = -8

-3 + 3 = 0

-1 + 9 = 8

Observation: No two such factors can be found !!

Conclusion: Trinomial can not be factored

The equation at the end of step

1

:

x2 - 5x - 9 = 0
