2x2-5x+12th Bipudi writes as siguik...
pls ans this que​

Answer 1

Step-by-step explanation:

(1): "x2" was replaced by "x^2".

Step by step solution :

STEP

1

:

Equation at the end of step 1

(2x2 - 5x) - 12 = 0

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 2x2-5x-12

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

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

The last term, "the constant", is -12

Step-1 : Multiply the coefficient of the first term by the constant 2 • -12 = -24

Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -5 .

-24 + 1 = -23

-12 + 2 = -10

-8 + 3 = -5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 3

2x2 - 8x + 3x - 12

Step-4 : Add up the first 2 terms, pulling out like factors :

2x • (x-4)

Add up the last 2 terms, pulling out common factors :

3 • (x-4)

Step-5 : Add up the four terms of step 4 :

(2x+3) • (x-4)

Answer 2

thanks to flw dear

The non-metals are elements on the right of the periodic table. Non-metals can be gases, liquids or solids. ... Non-metals don't conduct electricity well: they are insulators. There is one exception: graphite is a non-metal which can conduct electricity.
