Question

5x2-4-8x by splitting the middle term

Answer 1

Answer:

$\huge\orange {(5x + 2)(x - 2)}$

Step-by-step explanation:

According to the Q,

$> > 5 {x}^{2} - 4 - 8x$

$> > 5 {x}^{2} - 8x - 4$

Sum = (-8)

Product = -4 x 5 = (-20)

$> > 5 {x}^{2} - 10x + 2x - 4$

$> > 5x(x - 2) + 2(x - 2)$

$\orange {> > (5x + 2)(x - 2)}$

Answer 2

Step-by-step explanation:

ANSWER:-

Given : 5x²-8x-4

Using Middle Term Split

The factors of (5×4)=20 are 10x and 2x( as it fulfills the condition of the middle term).

So, our Equation will be

= 5x²-10x+2x-4

=5x(x-2)+2(x-2)

= (5x+2)(x-2)
