Factor. t^2 + 8t + 7 ____

Identify Variables: Identify a, b, and c in the quadratic expression t^2 + 8t + 7. Compare t^2 + 8t + 7 with the standard quadratic form ax^2 + bx + c. Here, a = 1, b = 8, and c = 7.Find Two Numbers: Find two numbers that multiply to c (7) and add up to b (8). We need to find two numbers m and n such that: m * n = 7 (product of c) m + n = 8 (sum of b) The numbers 1 and 7 satisfy these conditions because: 1 * 7 = 7 1 + 7 = 8Write Factored Form: Write the factored form using the numbers found in Step 2. The factored form of the quadratic expression is (t + m)(t + n). Substitute m = 1 and n = 7 into the factored form to get: (t + 1)(t + 7)

t^2 + 8t + 7

Identify Variables: Identify $a$ , $b$ , and $c$ in the quadratic expression $t^2 + 8t + 7$ . Compare $t^2 + 8t + 7$ with the standard quadratic form $ax^2 + bx + c$ . Here, $a = 1$ , $b = 8$ , and $c = 7$ .
Find Two Numbers: Find two numbers that multiply to $c$ ( $7$ ) and add up to $b$ ( $8$ ). $\newline$ We need to find two numbers $m$ and $n$ such that: $\newline$ $m \times n = 7$ (product of $c$ ) $\newline$ $m + n = 8$ (sum of $b$ ) $\newline$ The numbers $7$ $0$ and $7$ satisfy these conditions because: $\newline$ $7$ $2$ $\newline$ $7$ $3$
Write Factored Form: Write the factored form using the numbers found in Step $2$ . $\newline$ The factored form of the quadratic expression is $(t + m)(t + n)$ . $\newline$ Substitute $m = 1$ and $n = 7$ into the factored form to get: $\newline$ $(t + 1)(t + 7)$
