Question

2 x² - 7x + 2 for x = 1 ​

Answer 1

Answer:

-3

Step-by-step explanation:

2 x² - 7x + 2

= 2×$1^{2}$ -(7×1) + 2

= 2 - 7 + 2

= 4 - 7

= -3

Answer 2

• As per the data given in the question, we have to find the value of the expression.

           Given data:- $2x^{2} -7x+2.$  for $x=1.$

           To find:- Value of the given expression.

           Solution:-

• We will take the LCM of the denominators, and make denominators the same.

• We will Convert the given fractions to equivalent fractions with the denominator as the LCM.

• Adding the numerators over the denominators.

              $2x^{2} -7x+2\\=2(1)^{2} -7(1)+2\\=-3.$

      Hence we will get the final value $-3.$
