Select the two values of x that are roots of this equation.<br> X2 + 2x - 5 = 0
LenaWriter [7]

Answer:

x=-1+\sqrt{6 }

x=-1-\sqrt{6 }

Step-by-step explanation:

x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}

Ignore the A before the ±. It wouldn't let me type it correctly.

x² + 2x - 5 = 0

a = 1

b = 2

c = - 5

x=\frac{-2±\sqrt{2^{2}-4((1)(-5)) } }{2(1)}

x=\frac{-2±\sqrt{4-4((1)(-5)) } }{2(1)}

x=\frac{-2±\sqrt{4+20 } }{2(1)}

x=\frac{-2±\sqrt{24 } }{2}

x=\frac{-2±\sqrt{(2)(12) } }{2}

x=\frac{-2±\sqrt{(2)(2)(6) } }{2}

x=\frac{-2±\sqrt{(2)(2)(2)(3) } }{2}

x=\frac{-2±(\sqrt{2} )(\sqrt{2})(\sqrt{(2)(3) )} }{2}

x=\frac{-2±2\sqrt{6 } }{2}

Two separate equations

x=\frac{-2+2\sqrt{6 } }{2}

x=\frac{-2-2\sqrt{6 } }{2}

x=-1+\sqrt{6 }

x=-1-\sqrt{6 }

Solve the system of linear equations by substitution
Elodia [21]
X= 5y + 1

-2x + 9y = -1

-2(5y + 1) + 9y = -1

-10y - 2 + 9y = -1

-y - 2 = -1

-y = 1

y = -1

x + 5 = 1

x = -4

(-4, -1)

Solve for X ??? <br><br> A. 2 / 15<br> B. 20<br> C. 30<br> D. / 35
Finger [1]

Answer:

2 sqrt(15)

Step-by-step explanation:

Using the secant tangent formula

(whole secant) x (external part) = (tangent)^2

(5+7) * 5 = x^2

12*5 = x^2

60 = x^2

Taking the square root

sqrt(60) = sqrt(x^2)

sqrt(4*15) = x

2 sqrt(15) =x
