Question

simplify 5x²-2x-9=0​

Answer 1

Answer:

STEP

1

:

Equation at the end of step 1

(5x2 - 2x) - 9 = 0

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 5x2-2x-9

The first term is, 5x2 its coefficient is 5 .

The middle term is, -2x its coefficient is -2 .

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

Step-1 : Multiply the coefficient of the first term by the constant 5 • -9 = -45

Step-2 : Find two factors of -45 whose sum equals the coefficient of the middle term, which is -2 .

-45 + 1 = -44

-15 + 3 = -12

-9 + 5 = -4

-5 + 9 = 4

-3 + 15 = 12

-1 + 45 = 44
