Question

Find the roots of quadratic equations (x+5)(3x-1)=0

Answer 1

Step-by-step explanation:

multiplying

3x2-x+15x-5=0

3x2+14x-5=0

3x2+15x-x-5=0

3x(x+5)-1(x+5)=0

(3x-1)(x+5)=0

x=1/3, x=-5

plz mark it brainliast

Answer 2

(X +5) (3X - 1) = 0

3x² -x + 15x - 5 = 0

3X (X - 1 ) 5 ( 3X - 1) = 0

(3X + 5 ) ( X - 1 ) = 0

so X = $\huge\huge\huge\huge\frac{<strong>5</strong>}{<strong>3</strong>}$ and X = 1
