sleet_krkn [62]

Concentrate on the numbers alone. The GCF of 35, 14 and 63 is 7.

You know y^4 goes into every number, so that'll be in your answer as well.

The final answer would be 7y^4.

$\\ \sf\longmapsto x^2-4x-5=0$

Use midterm splitation

$\\ \sf\longmapsto x^2-5x+x-5=0$

$\\ \sf\longmapsto x(x-5)+1(x-5)=0$

$\\ \sf\longmapsto (x-5)(x+1)=0$

$\\ \sf\longmapsto x=5\:or\:x=-1$

Solution is (-1,0) and (5,0)

Graph attached.

Spare way:-

Use quadratic formula .

$\\ \sf\longmapsto x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

$\\ \sf\longmapsto x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(-5)}}{2(1)}$

$\\ \sf\longmapsto x=\dfrac{4\pm \sqrt{16+20}}{2}$

$\\ \sf\longmapsto x=\dfrac{4\pm 6}{2}$

$\\ \sf\longmapsto x=\dfrac{10}{2}\:or\:\dfrac{-2}{2}$

$\\ \sf\longmapsto x=5\:or\:-1$
