Q. Factor as the product of two binomials.49−14x+x2=
Recognize the quadratic expression: Recognize the structure of the quadratic expression.The given expression is in the form of a quadratic trinomial, which can often be factored into the product of two binomials.The expression is 49−14x+x2.We can reorder the terms to match the standard form of a quadratic equation, which is ax2+bx+c.So, the expression becomes x2−14x+49.
Reorder the terms: Look for a pattern that matches the square of a binomial.The square of a binomial has the form (a−b)2=a2−2ab+b2.We can try to express x2−14x+49 in this form.Here, a2=x2, so a=x.We need to find b such that b2=49 and 2ab=14x.
Look for a pattern: Find the value of b.Since b2=49, b could be either 7 or −7.However, since we have −14x in the expression, we need to choose b=7 to get the middle term −14x (because 2ab=2×x×7=14x).So, b=7.
Find the value of : Write the factored form using the square of a binomial pattern.Now that we have and , we can write the expression as the square of a binomial:\newlinex^222 - 141414x + 494949 = (x - 777)^222.\newlineThis is the factored form of the expression as the product of two identical binomials.
