Click here to get an answer to your question ️ Q.3. Transcript. We have x2 – 5x + 6 – x2 – 3x – 2x + 6= (x – 3) (x – 2)So, the value of x2 – 5x + 6 is zero when x - 3 = 0 or x – 2 = 0i.e., when x = 3 or x = 2Therefore, the zeroes of x2 – 5x + 6 are 3 and 2.Sum of zeroes = = Product of zeroes Zeros of a polynomial can be defined as the points where the polynomial becomes zero on the whole. Degree of Zero Polynomial. Also verify the relationship between the zeroes and the coefficients in each case. Contact us on below numbers. Alternate Method. The degree of a polynomialis the highest power of the variable x. fill: #ffffff; (vi) Graph y = p(x) cuts the x-axis at three points, so the given polynomial has three zeroes. Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients. Wayne DeguMan. Find the numbers.10 added to thrice a w We have the quadratic polynomial x²+5x+6, So, the values of x²+5x+6 is zero when x+2=0 Or x+3=0, Therefore, the zeroes of x²+5x+6 are -2 and -3, This site is using cookies under cookie policy. -webkit-transform: translate(-50%,-50%); /* ]]> */ If α and β are zeros of the quadratic polynomial p(x) = x2 – (k + 6)x + 2(2k – 1), then find the value of k, if α + β = (αβ)/2 .?
