Question

2r^2 - 5r + 2 =0 plss solve this​

Answer 1

Answer:

(r-1) (2r-2)

Step-by-step explanation:

by middle term splitting

2r²-5r+2=0

2r²-3r-2r+2=0

2r(1-r) -2(r-1)

(r-1) (2r-2) Ans

Answer 2

To Find :

• we have to find value of r.

Solution :

Quadratic Equation : 2r² - 5r + 2 = 0

BY using quadratic formula:

$\boxed{ \boldsymbol{Quadratic \: formula = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} }}$

• a = 2
• b = -5
• c = 2

$\sf \: x= \frac{ - ( - 5) \pm \sqrt{ {( - 5)}^{2} - 4 \times 2 \times 2 } }{2 \times 2} \\ \\ \sf \: x = \frac{ 5\pm \sqrt{ 25 -16 } }{4} \\ \\ \sf \: x = \frac{ 5\pm \sqrt{ 9 } }{4} \\ \\ \sf \: x = \frac{ 5\pm 3}{4}$

x = 5 + 3/4 or 5-3/4

x = 8/4 or 2/4

• x = 2 or 1/2
