Question

5+34x-7x^2 factorise by quadriiotic method​

Answer 1

Answer:

5+34x-7x²= -7x²+34x+5 | (35x) (-x)

= -7x²+35x-x+5

= -7x(x-5)-1(x-5)

= (x-5) (-7x-1)

please mark me as brainliest.

Note: this is the splitting middle term method,this only need for quadratic equation. multiply the 1st and last term &

when we splitted , it should be equals to

multiply of 1st & last term and the resulting of middle term of given equation.
