x = 2 is not a root of the equation 2x2–7x–5=0.
Substitute the value of x in the quadratic equation, 2x2–7x–5=0.
8 - 14 - 5 = -11
Hence, 2 is not a root of the given quadratic equation.
State true or false. x=−1 is a zero of quadratic equation 3x2+7x+2=0.
x=3 is the solution of the equation x+3=0.
The remainder when f(x)=2x2−7x−1 is divided by x+3 is 38
x=9 is the solution of the equation 7x+1=50.
