Solve by factoring <br> 2x^2=19x+33
oksian1 [2.3K]

<span>2x^2 - 19x - 33 = 0 </span>

<span>The factors of 2 are 1 x 2. </span>
<span>The factors of 33 are 1 x 33 and 3 x 11. </span>

<span>Using Guess and Test and FOIL, find a combination that gives you a middle term of -19x: </span>

<span>(2x + 3)(x - 11) = 0. </span>

<span>Using the principal of zero product, solve each equation for x: </span>

<span>2x + 3 =0 and x - 11 =0. </span>

<span>The two solutions are x = -3/2 and x = 11.
