Whats the factor from of 2xy-4x plus 8y-16?
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
Factor 2xy plus 4x plus 8y plus 16?
2xy + 4x + 8y + 16 = 2[xy + 2x + 4y + 8] = 2[x(y + 2) + 4(y + 2)] = 2(y + 2)(x + 4)
What is the x-intercept of y equals -4x plus 4?
