The area of the triangle is eqaula to the sqare show that x²-3x-2=0​
agasfer [191]

Answer:

Step-by-step explanation:

Area of square = area of triangle

side*side = \dfrac{1}{2}b*h\\\\\\x*x=\dfrac{1}{2}*(x+1)(x+2)\\x^{2}=\dfrac{1}{2}[x*x +x*2+1*x+1*2]\\\\\\x^{2}=\dfrac{1}{2}[x^{2}+2x+x+2]\\\\\\x^{2}=\dfrac{1}{2}[x^{2}+3x+2]\\\\\\Multiply \ both \ sides \ by \ 2\\\\2x^{2}=x^{2}+3x+2\\\\2x^{2}-x^{2}-3x-2 = 0

x² - 3x - 2 = 0

Which equation has the solutions x=1+/- 5?
nikitadnepr [17]

Answer:

x^{2} -2x-4=0

Solving Steps

Use the quadratic formula

x=\frac{-(-2)(+/-)\sqrt{(-2)^2-4*1*(-4)} }{2*1}

Multiply / Remove the parentheses / Evaluate

x=\frac{2(+/-)\sqrt{4+16} }{2}

Calculate

x=\frac{2(+/-)\sqrt{20} }{2}

Separate the solutions

x=\frac{2(+/-)2\sqrt{5} }{2} \\x=\frac{2-2\sqrt{5} }2}

Simplify

x=1+\sqrt{5} \\x=1-\sqrt{5}
