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

$\\ \sf\longmapsto 2x^2+x=4$

$\\ \sf\longmapsto 8(2x^2+x=4)$

$\\ \sf\longmapsto 16x^2+8x=32$

$\\ \sf\longmapsto (4x)^2+2(4x)(1)=32$

$\\ \sf\longmapsto 4x^2+2(4x)(1)+1^2=32+1^2$

$\\ \sf\longmapsto (4x+1)^2=33$

$\\ \sf\longmapsto 4x+1=\pm\sqrt{33}$

$\\ \sf\longmapsto 4x=-1\pm\sqrt{33}$

$\\ \sf\longmapsto x=\dfrac{-1\pm\sqrt{33}}{4}$

navik [9.2K]

Y = x + b.

-4 = 2 x (-3/2) + b. -4 and 2 because of (2, -4). 2 is x and -4 is y.

b = 7.

Therefore, -4 = -3/2 + 7.
