Answer:
write in the form ax²+bc+c=0:
1.)x²-5x+14=0
2.)x²+x+5=0
3.)x²+10x+25=0
4.)4x²+9x-7=0
5.)2x²-13x-20=0
values of a,b,and c
1.)a=1,b= -5,c=14
2.)a=1,b=1,c=5
3.)a=1,b=20,c=25
4.)a=4,b=9,c= -7
5.)a=2,b= -13,c= -20
root 1:
1.)
2.)
3.)
4.)
5.)
Step-by-step explanation:
hanapin mo nalang yo g root tas add mo lagay mo lang sagot and product
1. x² - 5x = 14
•x² - 5x -14 = 0
•a = 1, b = -5, c = -14
•x1 = -2, x2 = 7
•-5
•-14
2. x² + x = 5
•x² + x - 5 = 0
•a = 1, b = 1, c = -5
•x1 = -1 - √21, x2 = -1 + √21
2 2
•-1
•-5
3. x² + 25 = 10x
•x² - 10x + 25 = 0
•a = 1, b = -10, c = 25
•x = 5
•5
•5
4. 4x² = 9x - 7
•4x² - 9x + 7 = 0
•a = 4, b = -9, c = 7
•x ∉ R
•x ∉ R
•x ∉ R
5. 2x² - 13x = -20
•2x² - 13x + 20 = 0
•a = 2, b = -13, c = 20
•x1 = 5, x2 = 4

•9
•20
