Question

(4 upon 2 x² +3 upon 2x) (5x²+3x

Answer 1

Answer:

Now, by doing middle term factorisation we get

⟼ x² - ( 3 -2 ) x - 6 = 0

⟼ x² - 3x + 2x - 6 = 0

⟼ x( x - 3 ) + 2 ( x - 3 ) = 0

⟼ ( x - 3) ( x + 2 ) = 0

so, Either ,

⟼ x - 3 = 0

⟼ x = 3

Or,

⟼ x + 2 = 0

⟼ x = -2

so, the roots of the quadratic equation are 3 , -2 .
