Ex 5.3 Class 11 Maths Question 4.
-x2 + x – 2 = 0
Solution.
We have, -x2 + x – 2 = 0
Comparing the given equation with the general form ax2 + bx + c = 0,we get
a = 1, b = 1, c = -2

Ex 5.3 Class 11 Maths Question 5.
x2 + 3x + 5 = 0
Solution.
We have, x2 + 3x + 5 = 0
Comparing the given equation with the general form ax2 + bx + c = 0, we get a = 1, b = 3, c = 5.

Ex 5.3 Class 11 Maths Question 6.
x2 – x + 2 = 0
Solution.
We have, x2 – x + 2 = 0
Comparing the given equation with the general form ax2 + bx + c = 0, we get a = 1, b = -1, c = 2.

Ex 5.3 Class 11 Maths Question 7.
$\sqrt { 2 } { x }^{ 2 }+x+\sqrt { 2 } =0$
Solution.
We have, $\sqrt { 2 } { x }^{ 2 }+x+\sqrt { 2 } =0$
Comparing the given equation with the general form ax2 + bx + c = 0, we get
