Steps for multiplying the given binomial and trinomial $(2x-3)\times (5x^{2}-2x+7)$ are:

Step 1: $2x\times (5x^{2}-2x+7)-3 \times (5x^{2}-2x+7)$

Step 2: $10x^{3}-4x^{2}+14x-15x^{2}+6x-21$

Step 3: $10x^{3}-19x^{2}+20x-21$

2x + 4(-6x + 12) = -84

2x - 24x + 48 = -84

-22x + 48 = -84

-22x = -84 - 48

-22x = -132

x = -132/-22

x = 6

hope this helps, God bless!
