Question

Factorise the expressions using the
common factor method.
A. 8x2y + 4x​

Answer 1

Answer:

$8x^{2}y + 4x = \red {4x}(2xy+1)$

Step-by-step explanation:

$Given \: expression \: 8x^{2}y + 4x$

$8x^{2} = \red { 2\times 2 } \times 2 \times \blue {x} \times x\times y$

$4x = \red { 2\times 2} \times \blue {x}$

$Common \:factors = \red { 2\times 2} \times \blue {x}$

$8x^{2}y + 4x = \red { 2\times 2} \times \blue {x}(2xy+1)\\= \red {4x}(2xy+1)$

Therefore.,

$8x^{2}y + 4x = \red {4x}(2xy+1)$
