Solve 3x2 - x = 10 I need help please!!

Answers

Answer:

3x^2 - x - 10 = 0

3x^2 - 6x + 5x - 10 = 0

3x(x - 2) + 5(x - 2) = 0

(3x + 5)(x - 2) = 0

x = -5/3 , 2

Step-by-step explanation:

mark me brainliest please

3x² - x = 10

3x² - x - 10 = 0

Δ = b² - 4.a.c

Δ = -1² - 4 . 3 . -10

Δ = 1 - 4. 3 . -10

Δ = 121

There are 2 real roots.

x = (-b +- √Δ)/2a

x' = (--1 + √121)/2.3    

x'' = (--1 - √121)/2.3

x' = 12 / 6    

x'' = -10 / 6

x' = 2    

x'' = -5/3
