Factorize: 3x2 + 10x + 8

1.	Factorize: 3x2 + 10x + 8
Answer» Given, 3x² + 10x + 8 Now first find the numbers whose Sum = 10 and Product = 3 × 8 = 24 Required numbers are 6 and 4, So we get; 3x² + 10x + 8 = 3x² + 6x + 4x + 8 = 3x(x + 2) + 4(x + 2) = (x + 2)(3x + 4)

Answer»

Given,

3x² + 10x + 8

Now first find the numbers whose

Sum = 10 and

Product = 3 × 8 = 24

Required numbers are 6 and 4,

So we get;

3x² + 10x + 8

= 3x² + 6x + 4x + 8

= 3x(x + 2) + 4(x + 2)

= (x + 2)(3x + 4)
