WebMar 30, 2024 · We need to check whether ( 7 + 3 x) is a factor of 3 x 2 + 7 x or not. Let us find out the root / zero of ( 7 + 3 x) . 7 + 3 x = 0 3 x = − 7 x = − 7 3 Root / Zero of 7 + 3 x is ( − 7 3) . Now, if ( 7 + 3 x) is a factor of given polynomial, then root of 7 + 3 x i.e. ( − 7 3) is also zero / root of the polynomial. Hence, we have root = − 7 3 Web= x2 +x −6 Explanation: The two brackets are multiplied by each other. To start, multiply the first term in the first bracket by the first term in the second bracket. = (x)(x) = x2 ... More Items Copied to clipboard
