Answer:

When p = -5 the answer is 45

Step-by-step explanation:

First, since p = -5, you have to plug -5 in as p into the equation

5(-5) + 2(-5)^2 +20 now we do pemdas, so we must fullfill the exponent

5(-5) +2 (25) + 20 now we multiply

-25 + 50 +20 now we add / subtract

25 + 20 and we continue adding

Answer:

Step-by-step explanation:

Substitute p = - 5 into the expression

5(- 5) + 2(- 5)² + 20

= - 25 + 2(25) + 20

= - 25 + 50 + 20

= - 25 + 70

= 45

Solve the equation 4s2+32s=60 by completing the square

lord [1]

Answer:

s = -4 ± √31

Step-by-step explanation:

Given 4 $s^{2}$ + 32s = 60

divide by 4 throughout

$s^{2} + 8s = 15\\s^{2} + 8s + (\frac{8}{2}) ^{2} = 15 + (\frac{8}{2}) ^{2}$

$(s + 4)^{2} = 31\\s + 4 = \sqrt{31}$

s = -4 ± √31

The roots of a certain quadratic equation is 1 and 2/3. Determine the equation

MrRa [10]

Answer:3x^2-5x+2=0

Step-by-step explanation:

Format of a quadratic equation= ax^2 +bx+c

Let x=1 and 2/3

When x=1

x-1=0.......(1)

When x=2/3

x-2/3=0.........(2)

Compare the equations

(x-1)(x-2/3)=0

x^2-2/3x-x+2/3=0

x^2-5/3x+2/3=0

Multiply all terms by 3

3x^2-5x+2=0
