Question :-
Factories 20x² - 26x + 8 .
Answer :-
→ Factors are 1/2 and 4/5 .
Solution :-
If we need to solve any Quadratic then take it equal to zero (0)
Let given Quadratic is p(x) ,
Then P(x) = 0,
→ 20x² - 26x +8 = 0
→ 20x² - 10x - 16x +8 = 0
→ 10x(2x - 1) - 8(2x -1) = 0
→ (2x -1)(10x - 8 ) = 0
• Case (1) if
→ 2x -1 = 0
→2x = 1
→ x = 1/2
• Case (2) if
→10x - 8 = 0
→ 10x = 8
→5x = 4
→ x = 4/5
