HW 5.5 REDO

Determine the values of a, b, and c for the quadratic equation:

4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Use the quadratic formula to find the solutions for

y = -x² - 5x + 12

• No Real Solution

• 
• 
• 

What should you do first in solving this equation?

x² + 6x - 13 = 3

• Factor

• Write down: a = 1, b = 6, c = -13

• Subtract 3 from both sides.

• Add 3 to both sides.

Solve using the quadratic formula...

9x² = 4 + 7x

• No solution

Identify a, b and c in the quadratic equation: $2x^2-3x-5=0$   

• a = 2 , b = 3, c = -5

• a = 2, b = -3, c = 5

• a = 2, b = -3, c = -5

• a = -2, b = 3, c = 5

 $m^2-5m-14=0$  

• x = 7 and -2

• x = 7 and 2

• x = -7 and -2

• x = -7 and 2

 $2x^2-36=x$  

•  $x=\frac{-9}{2}and\ 4$  

•  $x=\frac{9}{2}\ and\ -4$  

•  $x=4\ and\ -4$  

• No real solution
