Question

Factorise the given expression:- ​

Answer 1

Step-by-step explanation:

$\huge\underline\purple{\mathfrak</p><p>Your Answer}$

Expression is - 7√2x²-10x²-4√2

Solution:- Here , 7√2 x (-4√2)= -56

So, we split -10 into two parts whose sum is -10 and product is -56.

=> Clearly, (-14+4)=-10 and (-14) x 4= -56

So, 7√2x² -10x -4√2 = 7√2x²-14x+4x-4√2

=> 7√2x(x-√2) + 4(x-√2)

=> (x-√2) (7√2x + 4).

Hence,(7√2x²-10x-4√2)= (x-√2)(7√2x+4)

Answer 2

Answer:

Step-by-step explanation:

Mulitply 7$\sqrt{2}$$x^{2}$ and 4$\sqrt{2\\}$ and factorize it. you will get -14 and 4

7$\sqrt{2}$$x^{2}$-14x+4x-4$\sqrt{2}$

=> 7$\sqrt{2}$x(x-$\sqrt{2}$) +4 (x-$\sqrt{2}$)

=> x=$\sqrt{2}$ or x=-4/7$\sqrt{2}$

the factors are $\sqrt{2}$ and -4/7$\sqrt{2}$
