Question

iv) 5x² + 3x - 2 = 0​

Answer 1

Answer:

x= (–1) , 2/5

Step-by-step explanation:

5x² + 3x – 2 = 0

or, 5x² +5x – 2x – 2= 0

or, 5x(x+1) –2(x+1) = 0

or, (x+1)(5x–2)

therefore, x =(–1) or 2/5

Answer 2

Answer:

5x²+3x-2=0

5x²+(5-2)x-2=0

5x²+5x-2x-2=0

5x(x+1)-2(x+1)=0

(5x-2)(x+1)=0

5x-2=0 x+1=0

X=2/5 x=-1

X=(2/5,-1)
