Question

2x saqure +15x + 4=0​

Answer 1

Answer:

2x2 - 15x) - 4 = 0

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 2x2-15x-4

The first term is, 2x2 its coefficient is 2 .

The middle term is, -15x its coefficient is -15 .

The last term, "the constant", is -4

Step-1 : Multiply the coefficient of the first term by the constant 2 • -4 = -8

Step-2 : Find two factors of -8 whose sum equals the coefficient of the middle term, which is -15 .

-8 + 1 = -7

-4 + 2 = -2

-2 + 4 = 2

-1 + 8 = 7

Observation : No two such factors can be found !!
