Factor the following expressior \[ \begin{array}{l}7 x^{2}+15 x+2 \\ ([?] x+[])(x+[])\end{array} \]

Factor the expression by following steps: - step0: Factor: \(7x^{2}+15x+2\) - step1: Rewrite the expression: \(7x^{2}+\left(1+14\right)x+2\) - step2: Calculate: \(7x^{2}+x+14x+2\) - step3: Rewrite the expression: \(x\times 7x+x+2\times 7x+2\) - step4: Factor the expression: \(x\left(7x+1\right)+2\left(7x+1\right)\) - step5: Factor the expression: \(\left(x+2\right)\left(7x+1\right)\) La expresión \( 7 x^{2}+15 x+2 \) se puede factorizar como: \[ (7x+1)(x+2) \] Por lo tanto, la factorización es: \[ ([7] x+[1])(x+[2]) \]
