Factorize the following 3x2 - 10x + 8.
Solution:
We will factorize the polynomial 3x2 - 10x + 8 to find the value of x by splitting the middle term.
Step 1: Identify the values of a, b and c.
In the above equation, a is coefficient of x2 = 3, b is the coefficient of x = - 10 and c is the constant term = 8.
Step 3: Multiply a and c and find the factors that add up to b.
3 × (8) = 24
⇒ - 6 and - 4 are the factors that add up to b.
Step 4: Split bx into two terms.
3x² - 6x - 4x + 8 = 0
Step 5: Take out the common factors by grouping.
3x(x - 2) - 4(x - 2) = 0
(3x - 4) (x - 2) = 0
By putting the factors equal to zero we get two values of x
3x - 4 = 0 and x - 2 = 0
x = 4/3 and x = 2
Factorize the following 3x2 - 10x + 8.
Summary:
The factors of the equation 3x2 - 10x + 8 are x = 4/3 or x = 2.
