`3x+7=12 ,5/2x-9=1,\ x^2+1\ \ a n d\ x/3+5=x/2-3` are equations in one variable `xdot`

Solve : 3x+7=12 ,5/2x-9=1\ a n d\ x/3+5=x/2-3 are equations in one variable xdot

3x+7=12,(5)/(2)x-9=1,x^(2)+1 and (x)/(3)+5=(x)/(2)-3 are equations in one variable x.

Add ; 7x^2-4x+5,\ -3x^2+2x-1\ a n d\ 5x^2-x+9.

3x-2-7,3/2x+9=1/2, y/3+(y-2)/4=5 are linear equations in one variable, because the highest power of the variable in each equation in one whereas the equations 3x^2-2x+1=0, y^2-1=8 are not linear equations, because the highest power of the variable in each equation is not one. In this chapter, we shall study linear equations in one variable only.

If (2x^2-3x+1)(2x^2+5x+1)=9x^2 ,then equation has

Add 7x^(2)-4x+5,-3x^(2)+2x-1 and 5x^(2)-x+9

Write t for ture and f for false for each of the following: 1. In-x, the constant trem is -1 2. The coefficient of x in x^2-3x+5 is 3. (5x-7)-(3x-5)=2x-12 4. (3x+5y)(3x-5y)=(9x^2-25y^2) 5. If a=2 and b= 1/2 then value of ab(a^2+b^2) is 4.1/4

If |2xx+3 2(x+1)x+1|=|1 5 3 5| , then write the value of xdot

1 + 5x + 3y = 9 2x 3y = 12 X = (x, y) - 4

Solve : (2x^2 - 3x+1) (2x^2 + 5x + 1) = 9x^2 .
