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
