Question

factorise this 36×^2 + 84× + 49​

Answer 1

Answer:

$({6x + 7})^{2}$

Step-by-step explanation:

we can write

we can write 36x^2 as

$( {6x})^{2}$

and we can also write 49 as

${7}^{2}$

and 84 x can be written as 2*(6x)*(7)

so we can write it as

1. $({6x})^{2} + 2 \times 6x \times 7 + {7}^{2}$

as it is in the form of

${a }^{2} + 2ab + {b}^{2}$

so we can write it as

$({a + b})^{2}$ 2.

$( {6x + 7})^{2}$
