$3x^{2}+16x-35$
$(x+7)(3x-5)$ FOIL --> First, Outer, Inner, Last Multiply the first numbers together: $x \times 3x = 3x^{2}$ Multiply the outer numbers together: $x \times -5 = -5x$ Multiply the inner numbers together: $7 \times 3x = 21x$ Multiply the last numbers together: $7 \times -5 = -35$ Add together and simplify: $3x^{2}+21x-5x-35$ $3x^{2}+16x-35$
