Solve the following quadratic equations by extracting square roots.Answer the questions that follow.

Vikentia [17]

Answer:

1. x=±4

2. t=±9

3. r=±10

4. x=±12

5. s=±5

Step-by-step explanation:

1. x^2 = 16

Taking square root on both sides

$\sqrt{x^2}=\sqrt{16}\\\sqrt{x^2}=\sqrt{(4)^2}\\$

x=±4

2. t^2=81

Taking square root on both sides

$\sqrt{t^2}=\sqrt{81}\\\sqrt{t^2}=\sqrt{(9)^2}$

t=±9

3. r^2-100=0

$r^{2}-100=0\\r^2 =100\\Taking\ Square\ root\ on\ both\ sides\\\sqrt{r^2}=\sqrt{100}\\\sqrt{r^2}=\sqrt{(10)^2}$

r=±10

4. x²-144=0

x²=144

Taking square root on both sides

$\sqrt{x^2}=\sqrt{144}\\\sqrt{x^2}=\sqrt{(12)^2}$

x=±12

5. 2s²=50

$\frac{2s^2}{2} =\frac{50}{2}\\s^2=25\\Taking\ Square\ root\ on\ both\ sides\\\sqrt{s^2}=\sqrt{25}\\\sqrt{s^2}=\sqrt{(5)^2}$

s=±5 ..

The value of z when 4(.5z-10)=10z+4

GREYUIT [131]

Start by expanding the left hand side:

$4 \times 0.5 z + 4 \times (-10) = 10z+4$

which leads to

$2z -40 = 10z+4$

Now we want to move all terms involving the variable to the left hand side, and all constant terms on the right hand side:

$2z-10z = 4+40$

Simplify both sides by summing like terms:

$-8z = 44$

Divide both sides by -8 to solve for x:

$z = \cfrac{44}{-8} = -\cfrac{22}{4} = -\cfrac{11}{2} = -5.5$
