Solve `2x^2-5x+2=(5-sqrt(9+8x))/4` where `x lt 5/4`

(a) If f(x)=-x|x| , then find f^(-1)(x) and hence find the number of solution of f(x)=f^(-1)(x) (b) Solve 2x^(2)-5x+2=(5-sqrt(9+8x))/4 , where xlt5/4

Solve: 2x^(2)-5x+2=(5-sqrt(9+8x))/4 , where xlt5/4 .

Solve 2x^(2)-5x+2=(5-sqrt(9+8x))/(4) where x<(5)/(4)

Solve -5lt=(5-3x)/2lt=8.

Solve 9x+5=4(x-2)+8

Solve sqrt(4x-5)< x+2

Solve :sqrt(2x-6)+sqrt(x+4)=5

Solve: 2x-[3x-((2x-5))/8]=2x-9/4

Solve |5 - 4x| lt -2

Solve : sqrt(9+2x)-sqrt(2x)=(5)/(sqrt(9+2x)) .
