Consider the quadratic equation x squared = 4x - 5. how many solutions does the equation have?
snow_lady [41]

Answer:

The quadratic equation has two complex solutions

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2}=4x-5  

Equate to cero

x^{2}-4x+5=0  

so

a=1\\b=-4\\c=5

substitute in the formula

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

x=\frac{4(+/-)\sqrt{16-20}} {2}

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

Remember that

i^{2}=-1

so

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

x=2(+/-)i

therefore

The quadratic equation has two complex solutions

11111nata11111 [884]

f(4+h)-f(4)=(4+h)^2-10-(4^2-10)\\f(4+h)-f(4)=16+8h+h^2-10-16+10\\f(4+h)-f(4)=h^2+8h

What is the y-value in the solution to this system of linear equations?
Karolina [17]

Answer:

y = -4

Step-by-step explanation:

Solve the following system:

{4 x + 5 y = -12 | (equation 1)

3 y - 2 x = -16 | (equation 2)

Add 1/2 × (equation 1) to equation 2:

{4 x + 5 y = -12 | (equation 1)

0 x+(11 y)/2 = -22 | (equation 2)

Multiply equation 2 by 2/11:

{4 x + 5 y = -12 | (equation 1)

0 x+y = -4 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{4 x+0 y = 8 | (equation 1)

0 x+y = -4 | (equation 2)

Divide equation 1 by 4:

{x+0 y = 2 | (equation 1)

0 x+y = -4 | (equation 2)

Collect results:

Answer:  {x = 2 , y = -4
