Finding the Sum and Product of the Roots of Quadratic Equations - Grade 9 Mathematics

This video will demonstrate how to find the sum and product of the root of equations.

This is the formulas:

Sum of the roots: -b/a
Product of the Roots: c/a

Let us NOT SKIP THE ADS para in return kumita din ang katulad ni sir na nagtuturo para sa atin ng libre. More power sir.😊

Thankyou sir
1. x² - 5x - 9 = 0
Sum = 5
Product = -9
2.x²+7x+12=0
Sum=7
Product=12
3.3x²-x+4=0
Sum=3
Product=-3

[aryseeee]

1.
sum: 5
product: -9
2.
sum: -7
product: 12
3.
sum: 3
product: 4/3

[yuleille]

Done na po sir. Thank you po.

1. x² - 5x - 9 = 0
Sum = 5
Product = -9

2. x² + 7x + 12
Sum = -7
Product = 12

3. 3x² - x + 4 = 0
Sum = -⅓
Product = 4/3

Done reviewing Sr, Thanks po.(Galileo) 🥰❤

Let us NOT SKIP ADS for Teacher Gon. Thank you sir.😊

[airasalazar]

Thank you sir 😊 happy Teachers month 🌹❤️

[harleyjon]

hello po isa po ako sa mga supporters niyopo sa video
papareq po sana ako another example sa inequalities mga ganto po example
x2 over x2-3x-10 <0
yung ganyan po mabaha yung equations sa baba huhu wala po ako mahanap na example na ganyan nagbabakasakali lang po ;( thankyoupo <

[jhustinetulabut]

Palagi po ako nanonood sayo para matuto

[kotochigassu]

Sir thanks po sa tutorial nyo, sobrang laking tulong po ito pra sakin💚

[ishidamaruuuuu]

DONE.

x² - 5x -9 =0
Sum= 5
Product= -9

x² + 7x + 12=0
Sum= -7
Product = 12

3x² - x + 4 = 0
Sum= ⅓
Product= 4/3

[wwhgameplay]

thanks for teaching us, you are the best in math 😀

[mikaduarte]

Thanks po sir 9 galileo duarte
1.x^2-5x-9=0
Sum=5
Product=9

2.x^2+7x+12
Sum=-7
Product 12.

3.3^2-×+4=0
Sum=1/3
Product=4/3

[manjirou]

Thank you very much po, Sir!! Galileo here po! <3

[Blinku]

Thank you po dito finally 😅 nalilito po kasi ako pag dating sa -b/a kasi laging given ni ma’m ay - yung b pero nag tataka ako bakit pag nadivide eh positive yung answer eh negative nga yung b. But nung nakita ko to naintindihan ko na bakit. Tysm 🥰🥰

[bedrocklomby]

Pwede rin po ba factoring nalang lagi gamitin sa kada question na katulad niyan

[karlbenedictviri]

Done.

1. x^2 - 5x - 9 = 0
Sum = 5
Product = - 9

2. x^2 + 7x + 12 = 0
Sum = - 7
Product = 12

3. 3x^2 - x + 4 = 0
Sum = - 1/3
Product = 4/3

[lancesamonte]

Samonte (Galileo) done na po sir .diko lang po na gets pano naging -1 yung sum and product na -6 from -2 and -12 that is both over to 2

[ok-rdlj]

THANKS ULIT SIR, SAYO KO LANB NAGEGETS MGA 'TO HAHAHAHAHAAHAHAHSYYSS
