Answer 2

Given:

25 x^2-35 X + 12​

To find:

Factorise.

Solution:

From the given information, we have the data as follows.

25 x² - 35 x + 12​ = 0

As the above equation is the quadratic equation, so, we have,

a = 25

b = - 35

c = 12

The roots of the equation are:

x = [ -b ± √(b² - 4ac) ] / 2a

Substitute the values in the above equation.

x = [ -(-35) ± √((-35)² - 4 × 25 × 12) ] / (2 × 25)

x = [ 35 ± √(1225 - 1200) ] / 50

x = [ 35 ± √(25) ] / 50

x = [ 35 ± 5 ] / 50

x = [ 35 + 5 ] / 50  or   x = [ 35 - 5 ] / 50

x = [ 40 ] / 50  or   x = [ 30 ] / 50

x = 4/5  or x = 3/5

Therefore, the factors of 25 x² - 35 x + 12​ are 4/5 and 3/5
