The zeroes of the polynomial 3x2+11x−43x^2 + 11x - 4 are :

Answer: The zeroes of the polynomial are 13\frac{1}{3} and −4-4.

Step-by-step solution

Step 1: Identify coefficients

The given polynomial is a quadratic equation of the form ax2+bx+c=0ax^2 + bx + c = 0. We need to identify the coefficients aa, bb, and cc from the given polynomial 3x2+11x−43x^2 + 11x - 4.

Step 2: Apply the quadratic formula

To find the zeroes of a quadratic polynomial, we can use the quadratic formula. Substitute the values of a=3a=3, b=11b=11, and c=−4c=-4 into the formula.

Step 3: Substitute values and simplify

Substitute the identified values into the quadratic formula and perform the calculations. First, calculate the term under the square root, which is the discriminant.

Step 4: Calculate the discriminant

Calculate 112=12111^2 = 121 and 4(3)(−4)=−484(3)(-4) = -48. Then, 121−(−48)=121+48=169121 - (-48) = 121 + 48 = 169. The square root of 169 is 13.

Step 5: Find the two zeroes

Now, we separate the equation into two cases: one with the plus sign and one with the minus sign, to find the two distinct zeroes of the polynomial.
