Q. Factor the following expression completely.x4−16x2+3x3−48x+2x2−32Answer:
Rearrange terms in descending order: First, we should rearrange the terms in descending order of the powers of x to make it easier to factor.x4+3x3−16x2+2x2−48x−32Combine like terms.x4+3x3−14x2−48x−32
Combine like terms: Next, we look for common factors in groups of terms. We can group the first three terms and the last three terms separately. x4+3x3−14x2 - 48x+32
Group terms and find common factors: Now, factor by grouping. x2(x2+3x−14)−16(3x+2)
Factor by grouping: We can factor the quadratic x2+3x−14. x2(x−2)(x+7)−16(3x+2)
Factor quadratic expression: Now, we look for any common factors that can be factored out further, but there are none. So, the expression is completely factored.
