Question

Me ayudan resolviendo esta ecuacion porfavor
(2x-3)^2-(x+5)(4x-1)=-2(5-4)

Answer 1

(2X - 3)^2 - (X + 5)(4X - 1) = -2 (5 - 4)

(2X - 3)(2X -3) - (X + 5)(4X - 1) = -2(5 - 4)

(4X^2 - 6X - 6X + 9) - (4X^2 -X + 20X - 5 = -2(1)
-
4X^2 - 6X - 6X + 9 - 4X^2 + X - 20X + 5 = -2

-32X + X = -2 -9 -5

-31X = -16

X = -16/-31

X = 16/31

X = 0.5161




COMPROBACION

(2X-3)(2X-3)- (X+5)(4X-1)= -2(5-4)

(2(0.5161)-3)  (2(0.5161)-3) - (0.5161 + 5)(4(0.5161)-1)= -2(1)

(1.0322-3)(1.0322-3) - (0.5161+5)(2.0644-1) = -2(1)

(-1.9678)(-1.9678) - ( 5.5161)(1.0644) = -2(1)

3.872213684 - 5.87133684 = -2

- 1.999123156 = -2
