Question

3x^2+11x+10=0 by completing the square method ​

Answer 1

Step-by-step explanation:

3×10=30

WHEN when we add two numbers it should be equal to the addition of 11 and multiplying the same number we should get 30 so those two factors are 5 into 6 = 30 and when we add 5 + 68 = 11 so 3x^2+6x+5x+10=0

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

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

3x+5=0 so x=-5÷3

& x+2=0 so x=- 2
